摘要：
Disclosed is a refrigerator including an ultrathin wall type insulating wall having a reduced thickness while maintaining insulating performance, so as to increase the capacity of a storage chamber. A vacuum insulating material is disposed inside the insulating wall so as to ensure the insulating performance of the insulating wall, and a foam material, in the portion in which the vacuum insulating material is not disposed, is disposed to be thicker than a foam material in the portion in which the vacuum insulating wall is disposed, such that the insulating wall, which maintains insulating performance while maintaining the insulating wall having an overall ultrathin shape, can be formed. Furthermore, auxiliary vacuum insulating materials are additionally disposed in the insulating wall corner regions in which the vacuum insulating material is not disposed, such that the ultrathin wall-type insulating wall is formed while maintaining the overall insulating performance of the refrigerator, thereby reducing the t
