Document Type and Number:

WIPO Patent Application WO/2012/004901

Kind Code:

A1

Abstract:

Provided are a vacuum heat insulation member and a refrigerator provided therewith such that loads on a core member and an outer covering member are reduced, resulting in heat insulation performance being able to be secured for a long period of time. Said vacuum heat insulation member is equipped with the core member; and the outer covering member, which houses the core member, and the interior of which is depressurized. This vacuum heat insulation member is characterized in that cutouts are provided in first pieces of material of the core member; that a second piece of material the density of which is lower than that of the first pieces of material, and the thickness-wise deformation rate of which is larger than that of the same, is placed in overall contact with the first pieces of material; and that the second piece of material is bent toward the cutouts in such a way as to form recesses.
