In an elastic member, a first sheet layer and a second sheet layer are formed of a material having translucency. An elastic sheet can be visually recognized through the first sheet layer and the second sheet layer. First non-joint bands linearly continuous along a first direction intersecting an stretchable direction at an acute angle are repeatedly present at intervals in a direction orthogonal to the first direction as non-joint bands in which a portion not having sheet joined portions is continuous in an unfolded state in a stretchable region. Sheet joined portions and joint holes are provided at intervals between adjacent first non-joint bands in the stretchable region. A unit structure including a plurality of first non-joint bands having different first widths determined as widths in the direction orthogonal to the first direction is repeatedly present in the direction orthogonal to the first direction in the stretchable region.

A wet sheet which is hard to be fractured during production into a molded body, stable in shape, and easy to handle in processing, and a method for producing a molded body from the wet sheet. The wet sheet includes fine cellulose fibers having an average fiber diameter of 10000 nm or smaller, and pulp, wherein the wet sheet has a water content of 60 mass % or higher, and a thickness of 0.5 mm or more and 10 mm or less. A method for producing a molded body includes applying heat and pressure to a wet sheet to obtain a molded body, wherein the wet sheet includes fine cellulose fibers having an average fiber diameter of 10000 nm or smaller, and pulp, and has a water content of 60 mass % or higher, and a thickness of 0.5 mm or more and 10 mm or less.

An absorber has at least one continuous groove and a back sheet provided on a non-skin side with a plurality of adhesive displacement stoppers, for fixing the absorbent article to underwear. One continuous groove has a shape having two or more portions protruding toward a front of the continuous groove and/or having two or more portions protruding toward a rear of the continuous groove. The continuous groove includes a groove portion, where an imaginary region overlaps the continuous groove, the groove portion having an area of 3% or greater of the region, the groove portion not overlapping a centerline extending in the front-rear direction in plan view. The displacement stopper overlaps an entirety of the continuous groove in the width direction and an entirety of the groove portion in the front-rear direction, or does not overlap the groove portion, in plan view.

The problem is to provide excellent slipping-down preventive property with a simpler structure. This problem is solved by an attachable-type disposable wearing article configured so that, in the natural length state, as the unfixed area contracts, a pair of side areas of the end flap positioned lateral to the unfixed area are obliquely drawn closer as they extend backward, which results in formation of transverse portion extending in the width direction at the back edge of intermediate area located between the pair of side areas, while obliquely backward portions are formed at the back edges of the side areas positioned more backward as they extend laterally, and in the spread state, the back edge of the end flap extends along the width direction over the extent including from one of the obliquely backward portions to the other.

A disposable diaper includes a diaper body having a top sheet, a back sheet, and an absorber disposed therebetween, the disposable diaper extending from a backside portion to an abdominal side portion; a side flap provided in each of side portions of the backside portion, the side flap extending outward beyond the absorber in a width direction; and a fastening tape that is provided in the side flap to be fastened to the abdominal side portion when the diaper body is used. The fastening tape includes a fixed portion fixed to the side flap, and a protruding piece extending outward from the fixed portion in the width direction. The fixed portion includes a notch in a lower region that is closer to a leg side of a wearer than the protruding piece. The notch is recessed from an outer edge in the width direction toward an inner side.

Provided is a film-packaged tissue product collective pack containing a plurality of film-packaged tissue products gusset-packaged with an exterior film into a collective pack having a handle on its top face side, wherein the exterior film is a biomass film containing 10 mass % or less biomass raw material, has a degree of blocking of 120 mN or lower, and has a tensile elastic modulus in a TD direction of 380 to 460 MPa. The collective pack may be handled and manufactured in the same way as conventional collective packs, while reduction of environmental burden may be aimed through the use of biomass raw materials.

An individually packaged absorbent article, for which an absorbent article is individually packaged by a packaging sheet made of paper, wherein the packaging sheet is inwardly folded in a longitudinal direction with the absorbent article disposed inside the packaging sheet, and both edge portions in a transverse direction orthogonal to the longitudinal direction are sealed and form a seal part, the packaging sheet has tensile strength in the longitudinal direction that is 15 N/25 mm or less, and when peeling strength in the seal part between different portions of the packaging sheet is referred to as Ss and the tensile strength of the packaging sheet is referred to as Sw, Ss<Sw is satisfied.

In an elastic member, a first sheet layer and a second sheet layer are formed of a material having translucency. An elastic sheet can be visually recognized through the first sheet layer and the second sheet layer. First non-joint bands linearly continuous along a first direction intersecting an stretchable direction at an acute angle are repeatedly present at intervals in a direction orthogonal to the first direction as non-joint bands in which a portion not having sheet joined portions is continuous in an unfolded state in a stretchable region. Sheet joined portions and joint holes are provided at intervals between adjacent first non-joint bands in the stretchable region. A unit structure including a plurality of first non-joint bands having different first widths determined as widths in the direction orthogonal to the first direction is repeatedly present in the direction orthogonal to the first direction in the stretchable region.

A wiping sheet includes a patterned part of a fiber assembling base material and a non-patterned part of the fiber assembling base material. The patterned part includes cellulose nanofiber; and the non-patterned part does not include the cellulose nanofiber.

A disposable diaper whose absorber body changes its shape to motion of the wearer for enhanced fitting and wearing comfort, without excessively increased rigidity, includes an absorbent element having an absorber body and a wrapping sheet, and provided on its body side round and oval compressed areas, respectively. The round areas includes first and second compressed areas arranged respectively at intervals in the width and front-back directions, the second areas shifted from the first areas by half the intervals in the width and frond-back directions, the oval areas includes first compressed areas arranged between adjacent first round areas and between adjacent second round areas, with its major axis being aligned to the width direction, and second compressed areas, each arranged between first and second round areas with its major axis being aligned to a line connecting the first and second round areas.
