Anti-fog mirror and method for manufacturing the same

A method for manufacturing an anti-fog mirror comprising a transparent substrate, a reflecting film formed on a rear surface of the transparent substrate, a laminated film formed on a front surface of the transparent substrate, said laminated film being made of a TiO2 layer having a light transmission property and a photocatalytic function and a porous SiO2 layer having a light transmission property and a hydrophilic property laminated to each other with the porous SiO2 film constituting an external layer and imparting a hydrophilic property to the surface of the anti-fog mirror,

• said method comprising a step of forming the laminated film of the TiO2 layer and the porous SiO2 layer directly on the front surface of the transparent substrate by vacuum deposition in a state wherein the transparent substrate is heated to a temperature within a range from 200° C. to 450° C.
