<p><P>PROBLEM TO BE SOLVED: To provide a band-shaped vacuum heat insulating member easy to be formed long wherein the thickness of a container for storing a core material is uniform, a fin-like circumference is not formed, a gas barrier property is excellent. <P>SOLUTION: The vacuum heat insulating member 31 has a cylindrical casing molding body 32 manufactured by multi-layer extrusion molding, a permeable porous body 33 inserted in a pipe of the casing molding body 32 and a sealing member 35 fit and welded to an opening 34 of the casing molding body 32 and the inside of the pipe formed of the casing molding body 32 and the sealing member 35 is decompressed. The casing molding body 32 is molded by the multi-layer extrusion molding wherein a center layer is a polyethylene vinyl alcohol resin layer, the inner face of it is an inner polyolefin resin layer, the outer face of it is an outer polyolefin resin layer and an outer most layer face (a pipe outside surface) has a DLC coating layer 39. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
