To provide a photocatalyst coating film sufficiently excellent in durability of a substrate and/or coating while holding the decomposition activity (photocatalyst activity) and/or hydrophilicity of an organic substance at a high level by a photocatalyst immobilized on the surface of the substrate.
The photocatalyst film comprises a rutile type titanium dioxide and a compound showing high photocatalyst ability. The content of the rutile type titanium dioxide satisfies the conditions represented by the following formula (1): 4/X≤a≤100/X, wherein X represents the thickness (unit: μm) of the photocatalyst coating film; and a represents the content (unit: % by mass) of the rutile type titanium dioxide to the total amount of the photocatalyst coating film.
