<P>PROBLEM TO BE SOLVED: To provide a vacuum heat insulation material that hardly receives breakage caused by an external force, and has superior handling performance. <P>SOLUTION: The vacuum heat insulation material constituted of a core material which is composed of at least a fiber aggregate and a film-shaped external wrapping material covering the core material and having gas barrier properties is characterized in that: an area of the external wrapping material is larger than an area of the core material; a region which protrudes exceeding a dimension of the core material is pasted by a thermal fusion layer of the external wrapping material when the core material is covered with the external wrapping material; the pasted region is bent in a shape along the core material and fixed to the external wrapping material with an adhesive tape; and the external face of the vacuum heat insulation material is covered with a hot-melt material. <P>COPYRIGHT: (C)2012,JPO&INPIT |
