Zusammenfassung:	To provide a photocatalyst coating agent that improves photocatalytic performance while suppressing desorption of the photocatalyst.SOLUTION: The photocatalyst coating agent contains at least two kinds of photocatalysts and a binder. At least two kinds of photocatalysts contains at least a first photocatalyst and a second photocatalyst. The first photocatalyst has the smallest average primary particle size among at least two kinds of photocatalysts. The second photocatalyst has the second smallest average primary particle size among at least two kinds of photocatalysts. The average primary particle size of the second photocatalyst is 2.0 or more times the average primary particle size of the first photocatalyst.SELECTED DRAWING: None 【課題】光触媒の脱離を抑制しつつ、光触媒性能を向上させる光触媒コート剤を提供する。【解決手段】光触媒コート剤は、少なくとも２種の光触媒と、バインダーとを含有する。少なくとも２種の光触媒は、第１光触媒と、第２光触媒とを少なくとも含有する。第１光触媒は、少なくとも２種の光触媒のうちで平均一次粒子径が最も小さい。第２光触媒は、少なくとも２種の光触媒のうちで平均一次粒子径が２番目に小さい。第２光触媒の平均一次粒子径は、第１光触媒の平均一次粒子径の２．０倍以上である。【選択図】なし
