The heat insulating layer 25 is comprised, for example from a vacuum heat insulating material, a foam heat insulating material, etc. Vacuum heat insulation material is sheet or plate heat insulation material. Foamed heat insulating materials include, for example, foamed polyurethane (also referred to as rigid urethane foam) and the like.

The vacuum insulation material is partially arranged inside the casing of the refrigerator and each door. Vacuum heat insulation materials are made by covering the core material with fine gaps such as glass wool or silicon dioxide powder with a gas-barrier outer covering material (bag-like body, such as a laminated film), and sealing the inside of the outer covering material under reduced pressure. form. The vacuum insulation material maintains its internal space as a high vacuum, which minimizes the heat transmitted in the gas phase, thereby achieving a high thermal insulation effect. As a material constituting the vacuum heat insulating material, conventionally known materials can be used.

Vacuum heat insulation materials are preferably arranged in the parts of the refrigerator that require high heat insulation. For example, in the refrigerator 1 , it is preferable to arrange a vacuum heat insulating material at a position facing the display panel 50 in the refrigerator compartment door 11 . Thereby, the heat generated from the display panel 50 can be blocked more reliably, and the heat insulation performance of the refrigerator compartment door 11 can be improved.

The camera mounting member 70 is mounted outside the protruding wall 32b on the open end side of the door back 31 (see FIG. 6 ).
