A vacuum heat insulation material has a covering material which is a lamination body including a sealant layer, a metal foil layer, a first plastic film layer, and a second plastic film layer which are laminated in this order from inside to outside via adhesive layers. When a foreign body is pierced into the vacuum heat insulation material, the propagation of breakage caused by the piercing is blocked somewhere inside the lamination body, thereby preventing the formation of through-pinholes. This results in the provision of a high-quality vacuum heat ins...
The invention claimed is: 1. A vacuum heat insulation material comprising at least a core material and a covering material, the covering material covering the core material and being vacuum sealed, wherein the covering material is a lamination body including at least two plastic film layers, one of a metal layer and a ceramic-deposited layer, and adhesive layers for joining therebetween, and the lamination body has a stress-relieving structure in inner layers thereof, the stress-relieving structure being able to prevent penetration and propagation of br...
