<P>PROBLEM TO BE SOLVED: To provide a heat insulating case body for a refrigerator with excellent cooling performance. Ž<P>SOLUTION: An outer space between an outer case and a vacuum heat insulating material and an inner space between the vacuum heat insulating material and an inner case are completely separated from each other by the vacuum heat insulating material, and the vacuum heat insulating material is installed in the entire region of a space between the outer case and the inner case so as to improve a covering ratio of the vacuum heat insulating material. The outer space between the outer case and the vacuum heat insulating material and the inner space between the vacuum heat insulating material and the inner case are kept well-balanced all the time. Thus, even if foamed heat insulating materials are filled in these spaces, the foamed heat insulating materials are foamed and grown in a well-balanced manner so as to provide the heat insulating case body with favorable quality. Therefore, the refrigerator has excellent cooling performance. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
