<p><P>PROBLEM TO BE SOLVED: To provide an epoch-making method of manufacturing a vacuum thermal insulation material and a method of manufacturing a thermal insulation body capable of developing such an acting effect that could have never hitherto been produced before. <P>SOLUTION: In this method of manufacturing the plate-like vacuum thermal insulation material formed of an outer plate body 1 and an inner plate body 2 and having a vacuum layer 3 created by vacuum heating between the outer plate part and the inner plate part, a heat resistant inclusion 4 capable of withstanding heating in the vacuum heating is disposed in a space S formed of the outer plate body 1 and the inner plate body 2 at a locking part 10 formed on at least one of the inner surface part of the outer plate body 1 and the inner surface part of the inner plate body 2, and the vacuum layer 3 is formed by vacuum-heating the space S. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
