There is provided a photocatalyst coating composition that is capable of forming a smooth and even photocatalyst coated film without the formation of aggregated particles. The photocatalyst coating composition according to the present invention includes photocatalyst particles, inorganic oxide particles other than the photocatalyst particles, a dispersion medium composed mainly of water, and a thickening agent, wherein the composition has a viscosity of 0 mPa·s or more to 10 mPa·s or less and, when the concentration of the composition is condensed tenfold, has a viscosity of not less than 40 mPa·s as determined under conditions of a shear rate of 1.0 s -1 and a temperature of 25°C with a rheometer. |
