The invention provides a heat insulation tank which can achieve fully thinning doors of refrigerators, etc., thereby enabling the expansion of the inside volume of the tank body. For an outer door plate (20), the outer side surface of a vacuum insulation panel (21) is enabled to abut the rear surface of the outer door plate (20), and the front surface of the inner door plate (22) is enabled to abut the inner side surface of the vacuum insulation panel (21), thereby forming a large refrigerating room door (17) (door) without using foamed polyurethane. According to this structure, the fully thinning of the large refrigerating room door (17) can be achieved, thereby enabling the expansion of the inside volume of the tank body. |
