A photocatalyst dispersion liquid contains titanium oxide particles, tungsten oxide particles, a phosphoric acid (salt) and a dispersion medium, and a containing amount of the phosphoric acid (salt) is from 0.001 mol times to 0.2 mol times with respect to the titanium oxide particles. In this photocatalyst dispersion liquid, the aggregation of the particles is suppressed and thus solid-liquid separation is not easily generated. According to this process for producing a photocatalyst dispersion liquid, titanium oxide particles are dispersed in a dispersion medium containing a phosphoric acid (salt) dissolved therein to obtain a titanium oxide particle dispersion liquid, and then tungsten oxide particles are mixed in the titanium oxide particle dispersion liquid.
