Disclosed is a vacuum heat insulating material. Also disclosed is a heat insulating box using the vacuum heat insulating material. The vacuum heat insulating material includes a core member and envelope members having gas-barrier properties and including heat-seal layers. The envelope members are opposed to each other in such a manner that the core member is disposed between the heat-seal layers. The envelope members are entirely heated to a temperature at which the heat-seal layers are melted, and the heat-seal layers are heat sealed to each other by ap...
1. A method of producing a vacuum heat insulating material, the method comprising: covering a core member with envelope members, each of the envelope members having a gas barrier layer and a heat-seal layer, wherein the envelope members are opposed to each other in such a manner to form an inside within which the core member is disposed,evacuating the inside of the envelope members; and subsequentlyfirst melting and sealing for heat sealing only the peripheries of the envelope members to provide heat-sealed peripheries by uniformly applying heat to the e...
