<p><P>PROBLEM TO BE SOLVED: To provide a vacuum heat insulating material having good heat insulating performance while producing less heat bridge phenomena that heat insulating effects are lowered with the transfer of heat through exterior bodies and maintaining high gas barrier performance of the exterior bodies and an inside vacuum condition for a long period. <P>SOLUTION: The vacuum heat insulating material 10 which is evacuated inside comprises a heat insulting core material 300 filled between the surface and rear exterior bodies. One of the surface and rear exterior bodies is a laminated film A100 which has an aluminum foil layer as a gas barrier layer in a structural layer, and the other is a laminated film B200 which has two barrier film layers in the structural layer, each consisting a number of inorganic oxide deposited layers as gas barrier layers. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
