Claims

[Scope of claims for utility model registration] 1. Thin outer panel made of metal material with low thermal conductivity 6
A reinforcing material 10 consisting of a reinforced synthetic resin base material 10a and a thermosetting adhesive 10b is arranged on the outer surface of the outer panel and 7, and the adhesive 9b is cured during the degassing heat treatment of this outer panel. A vacuum insulation material in which the thin outer plates 6 and 7 are configured to have a pressure resistance of 1 kg/cJ or more, the outer periphery of which is hermetically welded in a vacuum, and the inside is made into an electric atmosphere. 2 In addition to the getter 11 for gas adsorption, small-diameter glass wool fibers 13 are sealed at a low density inside a panel with a flat box structure in which the outer peripheries of the thin outer plates 6 and 7 are hermetically welded, and the outer circumferences of the thin outer plates 6 and 7 are sealed and welded. The vacuum heat insulating material according to claim 1, which is a registered utility model, characterized in that one or more metal foils 14 with low emissivity are provided in parallel with the plate surface.
