PURPOSE: To provide a member having satisfactory photocatalytic activity even by heat treatment at a low temp. CONSTITUTION: A binder layer 2 is formed on the surface of a substrate 1, a photocatalyst layer 3 is formed on the binder layer 2 so that it is partially embedded in the layer 2 and then the photocatalyst layer 3 is irradiated with light contg. >=1.7mW/cm<2> light of <=390nm wavelength to produce the object-ive member having photocatalytic activity. in other way, a layer consisting essentially of photocatalyst particles and a thermosetting resin is formed on the surface of a substrate and then irradiated with light contg. >=1.7mW/cm<2> light of <=390nm wavelength. |
