<p>PROBLEM TO BE SOLVED: To prevent the formation of a heat bridge, due to presence of a layered product, in a heat insulating layer of a heat insulating vessel. SOLUTION: A heat insulating vessel has a vacuum heat insulating vessel 1, an opening 2 formed on the vacuum heat insulating vessel 1, and a heat insulating lid 8 for closing the opening 2. In order to form the vacuum heat insulating vessel 1, a first heat insulative material 5 is charged between an outer vessel 3 and an inner vessel 4, and evacutating is performed between the outer vessel 3 and the inner vessel 4 to form a vacuum heat insulating layer 6. The heat insulating lid 8 is formed so as to enter the inner vessel 1 of the vacuum heat insulating vessel 1 from the opening 2. A layered product 13 prepared by alternatively laminating metal films and inorganic sheets is arranged along an inner surface of the inner vessel 4 on the side of the vacuum heat insulating layer 6 except for the entered heat insulating lid 8.</p> |
