The protruding portion 83 includes a first electrode 84 A and a second electrode 84 B electrically connected to the transparent conductive film 16.

A case to hold a movable unit, which is provided with an optical module and a flexible circuit board having one end connected to the optical module, in a swingable manner that the optical module is swingable, is provided. The case includes: a holder, swingable together with the optical module to house the optical module; a fixing portion, provided at the holder to fix the flexible circuit board; and a pedestal, provided at the holder and having a placing face along which the flexible circuit board is disposed at a side opposite to a side of the one end with respect to an area fixed to the fixing portion in the flexible circuit board, and the pedestal is provided in a configuration in which a swing center of the optical module is positioned on an extended line of the placing face.

An actuator includes a movable body provided with a magnet, a support body provided with a case and a coil assembly, a connecting body to be connected to the movable body and the support body, and a magnetic drive circuit. The coil assembly includes a first plate. The case includes a first case member, and a second case member. The coil assembly is positioned in a Z direction by fitting a protruding plate portion protruding from an edge of the first plate to an outer peripheral side into a first cutout concave portion provided in an edge of the first case member, and a second cutout concave portion provided in an edge of the second case member, and abutting a curved portion provided on an edge of each of the cutout concave portions against the protruding plate portion from both sides in the Z direction.

An optical unit with a runout correction function includes a reflection member, a camera module having a lens and an image pickup element, a holding member that rotatably holds the reflection member and also holds the camera module, and a fixing member that rotatably holds the holding member. A second rotation mechanism rotates the reflection member held in the holding member with an optical axis direction, which is a direction of an optical axis of the lens, as an axis direction of the rotation and is capable of runout correction in a yaw direction. In the optical unit with a runout correction function, when the runout correction in the yaw direction is performed, the image pickup element held in the holding member is rotated together with the reflection member with the optical axis direction as the axis direction of rotation.

An optical unit comprises a movable body, a fixed body, a rotation support mechanism, and a gimbal mechanism, in which the movable body has a first side surface, a second side surface, a third side surface, and a fourth side surface as movable-body side surfaces, the first side surface positioning on an opposite side to the third side surface, and the second side surface positioning on an opposite side to the fourth side surface, a flexible printed circuit board is connected to the movable body on the first side surface side, has clearances provided with respect to the movable-body side surface, and has side-surface facing regions facing the movable-body side surface, and the side-surface facing regions are arranged to face the first side surface and the second side surface but not to face the third side surface and the fourth side surface.

A lens unit 1 includes a plurality of lenses aligned in a row along an optical axis L and a lens holder 2 . A first lens L 1 located the closest to an object-side La includes an object-side lens surface 11 , an image-side lens surface 12 , and an image-side flange surface 13 . A first housing portion 4 accommodating the first lens L 1 in the lens holder 2 includes a regulation portion 42 regulating a position of the first lens L 1 in the optical axis L direction. The regulation portion 42 includes a lens seating surface 40 in contact with the first lens L 1 . The image-side flange surface 13 of the first lens L 1 includes an outer peripheral region 13 A in contact with the lens seating surface 40 of the regulation portion 42 and an inner peripheral region 13 B in which a flexible printed circuit board 8 is disposed.

An O-ring seals between a first lens and a lens barrel. Further, between the second lens and the lens barrel is also sealed by a first adhesive layer. The lens barrel, in a state before manufacturing of the lens unit, is provided with a communication passage that communicates an inside of the lens barrel with an outer peripheral groove (outside of the lens barrel. The communication passage, in the state of FIG. 1 after manufacturing, is sealed by a second adhesive layer (third seal member) made of an adhesive.

In a motor, a wire terminal, to which an end at an end of winding of a wire is connected, is held by an insulator that is held by a stator core. The wire terminal comprises: a substrate connection section; plural legs held by a split insulator; a plate section, a thickness direction of which faces a radial direction, between the legs and the substrate connection section; and a wire connection section, a portion of which projected from the plate section is bent to hold the wire on an inner side. An elastic section is a meandering section meandering to turn back in a circumferential direction between the plate section and the substrate connection section, and extends from an end on another side in the circumferential direction of the plate section toward the substrate connection section.

An optical unit includes: a reflective portion that reflects, on a reflective surface, an incident light flux incident from the outside in a reflection direction toward an imaging element from an incident direction; a movable body to which the reflective portion is fixed; and a fixed body. In the movable body, emboss processing is applied to at least one of a reflective surface contact surface in contact with the reflective surface, and a side surface contact surface in contact with a side surface of the reflective portion on a side of an intersecting direction intersecting with the incident direction and the reflection direction.

An actuator includes a connection body which is connected with a support body and a movable body and is provided with elasticity and/or viscoelasticity, and a magnetic drive mechanism structured to move the movable body with respect to the support body. The movable body may include a support shaft, a tube-shaped part surrounding a magnet, a first inner frame part on one side of the tube-shaped part, and a second inner frame part on the other side of the tube-shaped part. The support body may include a first outer frame part, a second outer frame part, and a case surrounding the first and the second outer frame parts and the tube-shaped part. The connection body includes first and second connection bodies between the first and second inner frame parts and the first and second outer frame parts, and a third connection body between the tube-shaped part and the case.
