PROBLEM TO BE SOLVED: To surely detect the phenomenon which has occurred in skin, even when photographic discoloration of a test sheet, in any one of different photographing devices. SOLUTION: The test sheet may be provided with a reagent-holding part and a plurality of filter layers. The reagent-holding part holds a reagent, of which the color changes due to contact with an object to be tested generated from skin, and the plurality of filter layers are provided for different locations along the reagent holding part and transmit light of different wavelength regions. The test sheet may be provided with a reagent-holding part and a filter layer; the reagent-holding part holds a reagent of which the color changes due to contact with an object to be tested generated from skin; and the filter layer is provided for the side of the reagent-holding part opposite to its side in contact with skin and transmits light of part of the wavelength regions that a photo-detection part for detecting the color of the reagent can detect.
