気消費量が大きい欠点がある。BACKGROUND ART It is well known that fogging on glass can be prevented by maintaining the temperature of the glass surface at a temperature equal to or higher than the condensation temperature of steam. As specific methods, there are commercially available glasses with heating wires arranged inside the glass and mirrors with electric heaters arranged on the back side of the mirror. However, on glass with heating wires, the heating wires subtly obstruct the field of view, and mirrors
Since the thermal conductivity of the glass that constitutes the mirror is extremely low, it is difficult to sufficiently raise the temperature of the mirror surface to a predetermined temperature, and furthermore, there are disadvantages in that it consumes a large amount of electricity.

透明であるため、ガラスとしての本質を阻害しない。Effect: In the present invention, the glass surface is rapidly heated by supplying electricity to the conductive film described above. Since the current-carrying part is provided at a position extremely close to the surface layer of the glass, the temperature of the glass surface is quickly raised with a small current. Moreover, since the current-carrying part is covered with a metal oxide thin film, there is no risk of electrical leakage. Furthermore, since both the conductive film layer and the metal oxide thin film layer are transparent, the essence of glass is not impaired.
