<p>PROBLEM TO BE SOLVED: To provide a novel refrigerator capable of suppressing polyurethane foam from entering a storage groove formed by the vacuum insulation material and an inner wall surface of an outer case for storing a radiation piping element.SOLUTION: A storage groove storing a radiation piping element is formed in an end surface portion of a vacuum insulation material, and the end surface portion is fixedly attached to an inner wall surface of an outer case so as to surround the radiation piping element. Since the end surface portion of the vacuum insulation material is fixedly attached to the inner wall surface of the outer case so as to surround the radiation piping element, it is possible to suppress polyurethane foam from entering the storage groove storing the radiation piping element and to improve the heat insulation performance of the vacuum insulation material.</p> |
