PURPOSE: To suppress the change of surface resistance value with time by laying a resistance stabilizing film composed of a metal or an oxide of a metal or silicon between an intermediate film of safety glass and a transparent electroconductive film.

CONSTITUTION: In safety glass structure which comprises two or more glass plates 11, 15,... and a plastic intermediate film 12 arranged in the mutual contact faces of the glass plates and in which a transparent electroconductive film 13 and at least one pair of bus bar electrodes are formed on at least one contact face 17,... of these glass plates, one or more layers of a resistance value stabilizing film 14 composed of a metal or an oxide of the metal or silicon to suppress the change of a surface resistance value of the transparent electroconductive film 13 is laid between the transparent conductive film 13 and the plastic intermediate film 12. By the safety glass structure, since the change of resistance value of the transparent electroconductive film by ultraviolet light and heat can be suppressed, heat generation characteristics can be obtained for a long period of time when the safety glass structure is used as an anti-fogging glass of an electrically heating type for a vehicle to be driven by a high-voltage electric source especially such as an electric automobile.
