Document Type and Number:
Japanese Patent JP5130603
Kind Code:
B2
Abstract:
A member which comprises a substrate and, formed on and jointed to the surface thereof, a surface layer comprising a titanium oxide and an amorphous tungsten oxide which have photocatalytic activity, wherein the titanium oxide and an amorphous tungsten oxide are jointed with each other without forming a solid solution, and wherein the uppermost surface of the surface layer exhibits a hydrophilicity of 10 degree or less in terms of a water contact angle in response to the optical pumping by the radiation of light of 10 mu W/cm<2> or less in terms of the illuminance of ultraviolet rays; and a method for manufacturing the member. The member is capable of exhibiting excellent hydrophilicity in response both to a weak light of an internal lighting level and sunlight, even with a small amount of photocatalyst, and thereby having the resistance to fogging and staining.
