<p><P>PROBLEM TO BE SOLVED: To provide a heat insulating material capable of attaining required heat insulating performance and supplementing stiffness and shape-retention property of heat insulating layers by a shape retention member. <P>SOLUTION: The heat insulating material 1 is equipped with a core material 10 having heat insulating layers 12, 13 and the plastic-deformable shape retention member 11 laminated on the heat insulating layers 12, 13, having higher stiffness than the heat insulating layers 12, 13 and a vacuum pack 20 for covering around the core material member 10 for tightly sealing inside in a vacuum state. The required heat insulating performance can be attained by the heat insulating layers 12, 13 and the stiffness and shape-retention property of the heat insulating layers 12, 13 can be complemented by the shape retention member 11. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
