PROBLEM TO BE SOLVED: To obtain a photocatalyst supporting structure which supports a photocatalyst on the surface of a base material and at the same time exhibits intensified photocatalytic function, by applying a photocatalyst coating solution on the surface of the polymer base material followed by heat drying.;SOLUTION: A photocatalyst coating liquid containing a photocatalyst such as titanium oxide and a silicon compound is applied on a base material consisting of a polymer resin, e.g. vinyl chloride resin to form a photocatalyst layer, and the layer was heated and dried at a temperature of 30°C or higher and lower than 160°C to allow the photocatalyst to be supported on the surface of the base material. Further, the photocatalyst layer was subjected to a reheating treatment at a temperature higher than the above drying temperature and at 800°C or lower, preferably 150-800°C, more preferably 300-600°C for the length of time in which the base material does not deformed by blowing hot air on the photocatalyst, and then the photocatalyst layer is pressed onto the base material to obtain the objective photocatalyst supporting structure.;COPYRIGHT: (C)2000,JPO
