PROBLEM TO BE SOLVED: To prevent the deterioration of heat insulating performance and improve a production efficiency by a method wherein a vacuum heat insulating panel is installed at a position with a specified dimension from inner and outer plates while the generation of shrinkages on the surface of a member is eliminated. SOLUTION: A heat insulating wall member 50 is constituted of a first plate 51A, a first plate type heat insulating material 53A, consisting of a plastic form having a specified thickness, a vacuum heat insulating member 60, arranged above the first plate type heat insulating member 53A, the laminated body of a second plate type heat insulating member 53B, consisting of a plastic form having a specified thickness, and a second plate 51B, a first plate type heat insulating member 53A between the first plate 51A and the second plate 51B, and a first filling slab member 55A as well as a second filling slab member 55B, arranged in a part surrounded by the vacuum heat insulating member 60 and the second plate type heat insulating member 51B. In this case, the seal unit 65 of the vacuum heat insulating member 60 is constituted so as to be pinched by the first filling slab member 55A and the second filling slab member 55B. |
