REFRIGERATOR

PROBLEM TO BE SOLVED: To provide a refrigerator having a heat insulating box that can improve a heat insulating property by using a urethane resin and a vacuum heat insulating material together in a heat insulating layer, and that is sufficient with respect to strength.SOLUTION: In the refrigerator 1, a foaming heat insulating material is filled into a heat insulating space 13 formed between an outer case 9 made of a thin iron plate and an inner case 10 made of resin to form a heat insulating box 8. The heat insulating spaces are formed at least in the ceiling part, bottom part, rear-face part, and both side-face parts of the refrigerator respectively. In the heat insulating space formed in both side surface parts, a vacuum heat insulating material 12 is arranged at least at the middle between the outer and inner cases. A plurality of degassing holes 16 are formed in the outer case forming the heat insulating space wherein the vacuum heat insulating material, at a position facing the vacuum heat insulating material in detail, to extract a gas or air generated from the filled foaming heat insulating material to the outside of the refrigerator.
