A glass panel in which spacing members (2) are interposed between a pair of glass sheets (1A,1B) and a heat-fusible outer periphery sealing portion is provided along the entire outer periphery of the two glass sheets (1A,1B) for sealing the space (V) between the glass sheets (1A,1B) under a pressure-reduced condition. A linear expansion coefficient (.alpha.1) of one (1A) of the glass sheets (1A,1B) and a linear expansion coefficient (.alpha.2) of the other glass sheet (1B) are set within a range which satisfies a predetermined relation expression.
On décrit un panneau de verre constitué d'une paire de feuilles de glace polie (1A, 1B), d'éléments de maintien d'espace (2) interposés entre lesdites feuilles de glace polie (1A, 1B), et d'une partie de scellement de la circonférence externe de type à fusion thermique ménagée sur tous les bords extérieurs des deux feuilles de glace polie (1A, 1B) entre lesquelles un vide (V) est hermétiquement fermé dans des conditions de dépression. Des coefficients de dilatation linéaire ( alpha 1, alpha 2) sont établis pour la feuille de glace polie (1A) et la feuille de glace polie (1B), respectivement, dans une gamme de niveaux conformes à une expression relationnelle préétablie.
