PROBLEM TO BE SOLVED: To prevent the deterioration of mirror images, such as the double images and darkening of a mirror finished surface occurring in the presence of an optical semiconductor layer by providing the subject mirror with a base material having a light reflection surface and a front surface layer including the optical semiconductor formed on the light reflection surface of this base material and forming the mirror in such a manner that its front surface exhibits hydrophilicity in correspondence to the photoexcitation of the optical semiconductor. SOLUTION: This anti-fogging mirror used as dressing mirrors, bath room mirrors, mirrors for vehicles, road mirrors, etc., has the transparent base material having the reflection coating layer on its rear surface and the front surface layer contg. the optical semiconductor formed on the front surface of the transparent base material. The thickness of the transparent base material is set at <=0.5mm and the refractive index of front surface layer at <=2. The front surface layer is formed by incorporating titanium oxide particles and another material (low- refractive index material) in order to confine the refractive index of this layer to <=2 into the front surface layer. Silica, silicone or the mixture composed thereof is used for the low- refractive index material. The optical semiconductor particles, the titanium oxide particles and the particles of the low-refractive index material respectively having grain sizes of <=0.1μm are used. |
