Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a photocatalyst-coated body including a photocatalyst layer having good light resistance, in which discoloration with time due to irradiation with visible light is suppressed.SOLUTION: A photocatalyst-coated body includes at least a base material and a photocatalyst layer formed on a surface of the base material. The photocatalyst layer contains: visible light-responsive photocatalyst particles which include photocatalyst particles and at least one divalent copper compound; and a colored pigment. The absorbance of light at a wavelength of 460 nm in the photocatalyst layer is 0.20 to 0.37 (inclusive) as measured using an ultraviolet-visible-near infrared spectrophotometer.SELECTED DRAWING: Figure 1 【課題】可視光の照射による経時的な変色が抑制された、良好な耐光性を有する光触媒層を含む光触媒塗装体の提供。【解決手段】基材と、当該基材の表面に形成されてなる光触媒層とを少なくとも含んでなる光触媒塗装体であって、前記光触媒層が、光触媒粒子と少なくとも１種の２価銅化合物とを含む可視光応答型光触媒粒子と、有色顔料とを含んでなり、紫外可視近赤外分光光度計を用いて測定される、前記光触媒層の４６０ｎｍの波長における光の吸光度が０．２０以上０．３７以下である、光触媒塗装体。【選択図】図１
