To aim to provide a photocatalyst coating composition having a predefined photocatalytic function, which is to be formed as a coating film after being applied to a substrate and dried. The photocatalyst coating composition can improve adhesion property and abrasion resistance of the coating film. There is also provided a photocatalyst coating composition that has a shorter drying time after applied. The present invention provides a photocatalyst coating composition that is composed of a blend including: a graft copolymer of PTFE and perfluoro acid selected from the group consisting of perfluorosulfonic acid and perfluorocarbonic acid; a photocatalyst material; and at least one fluororesin selected from the group consisting of PVDF, PVF, PTFE, ETFE, PVDF-HFP, PCTFE, trifluorochloroethylene-alkyl vinyl ether copolymer, tetrafluoroethylene-alkyl vinyl ether copolymer, and trifluorochloroethylene-alkyl vinyl ether-alkyl vinyl ester copolymer.
