<p><P>PROBLEM TO BE SOLVED: To provide a vacuum heat insulating material which does not damage another member abutting on the vacuum heat insulating material, and a folding type cold insulating container improving durability and a cold insulating property by using the vacuum heat insulating material. <P>SOLUTION: A board-shaped core material 32 is covered by covering a jacket material 33 having a gas barrier property, and a vacuum heat insulating material body 31 reducing the pressure of the jacket material 33 and vacuum sealing that is covered by a storage bag 36, thereby forming the vacuum heat insulating material 5. Fin portions 33a to 33c on a peripheral edge of the jacket material 33 are folded and piled on a surface of the jacket material 33 corresponding to an involved part of the core material 32, and a pair or all of the vacuum heat insulating material body 31 on which the fin portions 33a to 33c are folded and piled is covered by the storage bag 36. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
