PROBLEM TO BE SOLVED: To provide a photocatalytic coating which has excellent adhesion to substances and normal temperature curability in the form of a film and is capable of including titanium dioxide as a photocatalyst in it in a high content. SOLUTION: The photocatalytic coating is prepared by mixing a liquid in which a photocatalytic source is added to an aqueous emulsion with a synthetic resin as a dispersion phase and a liquid containing an organic solvent. A fine powder of an ultraviolet-reactive titanium oxide photocatalyst excited by a light mainly composed of an ultraviolet light having a wavelength of not greater than approximately 400 nm and/or a fine powder of a visible light-reactive titanium oxide photocatalyst excited by a light mainly composed of a visible light having a wavelength of not shorter than approximately 380 nm is used for the photocatalytic source.
