To provide an inspection method of a photocatalyst substrate utilizing luminescence capable of discriminating clearly between a part where a photocatalyst layer is formed and a part where application of a photocatalyst coating agent (application liquid) is omitted by using various compounds coloring by being easily oxidized, and inspecting, simply at low cost in a short time, the part where the application of the photocatalyst coating agent is omitted.
This inspection method of the photocatalyst substrate utilizing luminescence is a method for bringing a solution containing materials luminescing by being oxidized into contact with the photocatalyst substrate formed by carrying the photocatalyst layer on a substrate. As the luminescent material, use is made of luminol, lucigenine, luciferin, bis (2, 4, 6-trichlorophenyl)oxalate and anthracene, bis (2, 4, 6-trichlorophenyl)oxalate and tetracene, bis (2, 4-dinitrophenyl)oxalate and anthracene, and bis (2, 4-dinitrophenyl)oxalate and teracene.
