PROBLEM TO BE SOLVED: To use a single-plate glass having an electrically conductive film without degradation or deterioration of a conductive film, by coating a glass material thick film comprising low melting point glass the having the value higher than a specified value of film thickness on the surface of the glass having an electrically conductive film. SOLUTION: If glass having an ingredient similar to that of base glass is used as glass material thick film and it is baked at the temperature exceeding its softening point to fuse the glass, the temperature of the base glass exceeds the softening point and the glass is softened deformed too, and a metal film can also be oxidized and deteriorated. Accordingly, low melting point glass having the softening point of 600 deg.C is suitable for use. A glass frit in which a particle diameter is 20μm or lower is used, it is dispersed in a polymer solution to knead paste, and the paste is applied on a glass plate covered with a conductive film by a means such as a flow coat method or screen printing or the like so as to form a film having thickness of 2μm after baking. Then, after drying, it is baked at a temperature higher than the softening point of the low melting point glass and lower than the softening point of a glass plate.
