<p><P>PROBLEM TO BE SOLVED: To provide a vacuum heat insulating material and its manufacturing method assuring excellent surface smoothness, managing flexibly with a design change, capable of being established simply, unlikely to damage its gas barrier film, and capable of preventing the heat insulating performance from dropping with time. <P>SOLUTION: The vacuum heat insulating material is structured so that a core material and a gas adsorbent are accommodated in a sack consisting of a gas barrier film and its inside is decompressed and sealed, wherein the core material is provided with a hole, which is filled with the gas adsorbent in the form of powder or granulated powder in the condition as it is as the gas adsorbent and is blocked with an aerating material. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
