Abstract
A method of forming a photo-catalytic film made of titanium oxide on a base material based on a simple process at low temperatures, particularly a method of forming a laminated material comprising photo-catalytic film of titanium oxide formed on a base material is provided. A method of forming a photo-catalytic film made of titanium oxide on a base material includes a treating process, in which photo-catalytic film of titanium oxide is formed on a base material and irradiated with UV light in vacuum or in an atmosphere of reducing gas at a temperature maintained between 25° C. and below 300° C.
