Abstract:
A member comprising: a substrate, and a surface layer provided on the substrate, wherein the surface layer comprises a hydrophobic resin and a photocatalytic oxide,the hydrophobic resin and the photocatalytic oxide being present in a microscopically dispersed and exposed state on the outermost surface of the surface layer, the photocatalytic oxide being hydrophilifiable in response to photoexcitation, and the presence of a hydrophobic portion derived from the hydrophobic resin exposed on the outermost surface, and a hydrophilic portion derived from the photocatalytic oxide exposed on the outermost surface, preventing hydrophilic materials and hydrophobic materials from being deposited on the surface of the member, thus permitting the surface of the member to be kept clean.
