    摘要: A photocatalyst according to the invention comprises a photocatalytic film of a compound of titanium and oxygen and is characterized in that the photocatalytic film is made porous and has 0.02 or higher value as a value calculated by dividing the arithmetical mean deviation of profile Ra with the film thickness. The photocatalytic film can also be specified by the intensity ratio between x-ray diffraction peaks of the anatase structure of titanium oxide. Such a porous photocatalytic material can be obtained by a reactive sputtering method in conditions of adjusting film formation parameters such as the film formation rate, the sputtering pressure, the substrate temperature, the oxygen partial pressure and the like in proper ranges, respectively, and the photocatalyst material is provided with excellent decomposition and hydrophilization capability.
