PROBLEM TO BE SOLVED: To provide a vacuum heat insulation panel that has an excellent gas barrier property.SOLUTION: An outer covering member 2 is formed by laminating a heat-seal layer 3, an adhesive layer 4, a barrier layer 5, an adhesive layer 6, a first protective layer 7, an adhesive layer 8, and a second protective layer 9 in order from the inner side. A vapour-deposited film 10 is formed on an inner surface of the heat-seal layer 3 and an outer surface of the heat-seal layer 3, wherein the vapour-deposited film 10 is made of metal or silica, and has an excellent gas barrier property. |
