To provide a photocatalyst member excellent in surface friction fastness, in particular, in wiping resistance so that the surface is hardly damaged and photocatalyst particles hardly separate from the surface.
The photocatalyst member A is made by making a photocatalyst layer 3 overlie the surface of a substrate 1 and further making a curable resin layer 4 having a thickness of 10-500 nm overlie the surface of the photocatalyst layer 3. Because the photocatalyst layer 3 is protected by the curable resin layer 4, the friction fastness, in particular, wiping resistance of the photocatalyst member A is enhanced, and anti-scratch property is enhanced. Because the curable resin layer 4 has a thin thickness of 10-500 nm, radical species and active oxygen species produced by activation of the photocatalyst particles in the photocatalyst layer 3 by light permeating through the curable resin layer 4 are scattered through the curable resin layer 4 to the front face side to decompose a malodor component and an organic substance of a low molecular weight and demonstrate antibacterial/antifungal actions.
