Abstract
A photocatalyst-coated body comprises 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 of zero parts or more by mass and less than 10 parts by mass, provided that a total amount of the photocatalyst particles, the dried substance of the inorganic oxide particles and the hydrolyzable silicone is 100 parts by mass in terms of silica. 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.
