Abstract: PURPOSE:To produce a vacuum heat insulating material pack industrially at low cost and obtain stable performance by charging a core member in a vessel, heat-sealing a peripheral part by means of a cover member while reducing pressure inside thereof, and forming non-deposited layers on the opposing side lines of the vessel. CONSTITUTION:A vacuum heat insulating material pack 1 is composed or a core member 2 made of an open cell hard urethane foam or the like, a vessel 6 which is prepared by vacuum-molding a plastic laminated film 5 having deposited layers 3 and non-deposited layers 4, and a cover member 8 made of a plastic-metal film laminated film 7. Since the deposited layer 3 of excellent barrier performance is provided on the vessel 6 and an accupying ratio of the non-deposited layer 4 in respect to the total surface area is small, adibator performance is hardly deteriorated, which otherwise may caused by deterioration of circularity due to temporal change. The non-deposited layer 4 is formed on a peripheral part of the vessel 6, so that it is possible to prevent heat leakage which may caused by the deposited layer 3, and to obtain stable performance. Since the vessel form is easily prepared, the pack can be produced ' industrially at low cost.
