In this way, when the air permeability in the housing is obstructed by the heat insulating panel 6, air and gas are easily accumulated in the portion having the residual space X, which causes voids in the rigid urethane foam 5. There was a problem that defective products were generated. Further, in the case structure of the refrigerator-freezer 1 b , the heat insulating panel 6 is fixed by being attached to the inner surface of the flat back plate 2 b , for example, so that the heat insulating panel 6 including the VIP 4 is attached to the back surface 2 b by its own weight. The plate 2 b might be deformed. Therefore, an object of the present invention is to improve the air permeability in the housing when the remaining space in the housing containing the heat insulating panel is filled with the foamed heat insulating material to perform sufficient degassing, thereby achieving the above-mentioned foaming. It is an object of the present invention to provide a housing structure of a storage that can minimize the generation of voids in a heat insulating material.
