Abstract
Provided are an ultraviolet-sensing sheet, an ultraviolet-sensing set, and an ultraviolet-sensing method, in which color gradation properties which are suitable for detecting an ultraviolet dose are obtained and in which the coloring of an ultraviolet-sensing layer caused by the effect of light other than ultraviolet light is prevented. An ultraviolet-sensing sheetincludes: a filter layerthat selectively allows transmission of light having a specific wavelength; and an ultraviolet-sensing layerthat includes a capsule including a color-forming dye and a photooxidant. It is preferable that the filter layerhas a maximum value of the transmittance in a wavelength range of 300 nm or longer and shorter than 380 nm.
