Abstract: Refrigerator door (25) includes outer packaging material (55) including a resin sheet, and a core material and gas adsorption each contained in outer packaging material (55). The gas adsorption device includes a vacuum sealed container containing a gas adsorbing substance that adsorbs various gases, an opening pin that opens the vacuum sealed container by a physical load from an outside, and a load-bearing spacer that suppresses displacement of the opening pin to less than or equal to a predetermined amount.

Abstract: A vacuum heat insulation material includes outer covering material which has a gas barrier property and a core material that is provided in an inside of outer covering material, the inside of the outer covering material being vacuum sealed, in which a sealed portion that is configured by sealing the peripheral edge of outer covering material, fin that is formed on the peripheral edge of outer covering material, and compressed portion which is formed by a protrusion being compressed, the protrusion is generated when the peripheral edge of outer covering material is folded back toward the core material are provided. Thereby, it is possible to provide a vacuum heat insulation material that is able to suppress reduction of a heat insulation property when a plurality of sheets are disposed lined up.
