Zusammenfassung:PROBLEM TO BE SOLVED: To provide a manufacturing method of a photocatalyst-coating liquid having dispersed therein a photocatalyst that hardly generates precipitates even when industrial water is used as a diluting medium, and a coating method of a photocatalyst particle. SOLUTION: The manufacturing method of the photocatalyst-coating liquid comprises diluting a thick dispersion of the photocatalyst comprising an aqueous medium and photocatalyst particles dispersed therein with diluting water in the co-presence of ammonium oxalate or ethylenediaminetetraacetic acid.
