<p>A carbon dioxide gas or a nitrogen gas is dissolved in a polyurethane raw material. By injecting the polyurethane raw material into the cavity of a mold formed in the periphery of a glass panel (2), a resin molded member (3) composed of a polyurethane foam is formed integrally with the glass panel (2). The specific gravity of the resin molded member (3) is set at not less than 0.60 but not more than 0.90 by changing the amount of the carbon dioxide gas or the nitrogen gas dissolved in the polyurethane raw material.</p> |
