PROBLEM TO BE SOLVED: To provide a composite material having a photocatalyst strongly fixed thereto and capable of keeping stable photocatalytic function over a long period of time, and also provide a method for producing the same. SOLUTION: A composite material having a photocatalytic function has an embedment of a photocatalytic substance 2 in a glass powder 1 in such a state that the surface thereof is exposed and can be produced by granulating the glass powder and a powdery photocatyst along with a binder to obtain a granular matter wherein the photocatalyst is bonded to the surface of the glass powder and heating the obtained granular matter to temp. equal to or lower than the flow temp. of glass to sinter the same and etching the sintered composite material by a glass etching soln. to embed photocatalyst particles in the glass powder so as to expose the surfaces of them to the surface of the composite material. |
