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 sheet 1 includes: a filter layer 10 that selectively allows transmission of light having a specific wavelength; and an ultraviolet-sensing layer 20 that includes a capsule including a color-forming dye and a photooxidant. It is preferable that the filter layer 10 has a maximum value of the transmittance in a wavelength range of 300 nm or longer and shorter than 380 nm.
