PROBLEM TO BE SOLVED: To produce a photo-catalytic film capable of being formed at a low temperature, having a sufficient flexibility, a good affinity and not so much different refractive index from a representative material having a visible light transmittance. SOLUTION: This photo-catalytic film having <=1.75 refractive index is produced by irradiating a raw material containing a thermally pre-polymerized silicone alkoxide polymer with ultraviolet light in an UV-C region.
