To succeed in an impact resistance test or a hot-back test by permitting a silane coupling agent to be interposed between a glass plate and a fluororesin film respectively so as to strengthen and raise the mutual joining force.
A fluororesin film 15 consisting of the copolymer of three kinds or more of monomers is interposed mutually between two sheets of glass plates 12, 13 being disposed face to face, and a silane coupling agent 16 made up of epoxy material is interposed between one glass plate 12 and the fluororesin film 15, and between the fluororesin film 15 and the other glass plate 13 respectively, so that the entirety of a fireproof glass plate 11 is formed through their integral joint adherence. For such a glass plate 12 or a glass plate 13, there are used, as a fireproof glass, e.g. gauze-reinforced glass, heat resistance crystal glass, or heat resistance strengthened glass.
