<p><P>PROBLEM TO BE SOLVED: To provide vacuum heat-insulating material which contributes to energy saving, a refrigerator using the vacuum heat-insulating material, and a manufacturing method of the vacuum heat-insulating material, by preventing reduction in general heat-insulating performance of the vacuum heat-insulating material. <P>SOLUTION: The vacuum heat-insulating material is composed of a core material and a jacket material to cover the core material so as to seal the inside of the jacket by decompression. The ear part extruded from the core material surface of the jacket material is bent so as to overlap and contact with the vacuum heat-insulating material surface side so that the ear part and the vacuum heat-insulating material surface come in contact with each other by interposing a heat insulating member, which can provide the vacuum heat-insulating material for reducing heat leakage. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
