摘要
The provision of beautiful colored titanium which is excellent in adhesion of the pure titanium or a titanium alloy with the base material, is excellent in photocatalytic activity, and further is excellent in design properties and a method of production of the same which is excellent in productivity and uses an anodic oxidation process is made the object. A titanium-based material having visible light response and excellent in photocatalytic activity characterized in that the material has pure titanium or titanium alloy as a base material, a thickness of a titanium oxide layer which is present on its surface is 0.1 µm to 5.0 µm in range, said titanium oxide layer contains anatase-type titanium dioxide and titanium bonded with hydroxy groups, and further said titanium oxide layer contains nitrogen and carbon respectively in 0.5 to 30 mass%.
