Patent ID: 8372774

Claim:
A photocatalyst-coated body comprising a substrate and a photocatalyst layer provided on the substrate, the photocatalyst layer comprising: photocatalyst particles of 1 part or more by mass and less than 20 parts by mass; inorganic oxide particles of 70 parts or more by mass and less than 99 parts by mass; and the dried substance of a hydrolyzable silicone in terms of silica of zero parts or more by mass and less than 10 parts by mass, provided that a total amount of the photocatalyst particles, the inorganic oxide particles and the hydrolysable silicone in terms of silica is 100 parts by mass, wherein the inorganic oxide particles have a number average particle diameter ranging from 10 nm or more to less than 40 nm calculated by measuring lengths of 100 particles randomly selected from particles located within a visible field magnified 200,000 times by a scanning electron microscope.
