A creation method for a calibration curve uses an antibody that has bindability to a target substance, and a fluorescently labeled substance in which the target substance is labeled with a fluorescent dye. The calibration curve is created on the basis of a degree of fluorescence polarization P 0 of a first reference sample that does not contain the target substance, and the degree of fluorescence polarization P cone of a calibration curve creation sample conc in which the concentration of the added target substance exceeds a concentration C Sα of the target substance.

A fluorescence polarization measurement device includes a light source unit, a polarization direction modulation element, a detector, and a controller. The polarization direction modulation element spatially modulates a polarization direction of the excitation light by a predetermined frequency, and emits, on a measurement target solution, the excitation light for which the polarization direction is spatially modulated by the predetermined frequency. The detector detects a spatial distribution of fluorescence intensity of the fluorescence having a polarization direction in a predetermined direction from among fluorescence emitted from the measurement target solution due to the excitation light. The controller extracts, from the detected spatial distribution of fluorescence intensity, a direct current component and a component having a frequency identical to the predetermined frequency, and calculates, based on the extracted component and the direct current component, a degree of polarization of the measurement target solution.
