<p><P>PROBLEM TO BE SOLVED: To prevent a convection space, particularly occurring at edge parts, from being formed in a vaccum heat insulating material usable as a heat insulating material for a refrigerant requiring heat insulation and a refrigerator using the vacuum heat insulating material. <P>SOLUTION: This vacuum heat insulating material comprises the core formed by storing a flexible inorganic fiber laminated body in the inner bag and an externally enclosing material formed of a film capable of preventing gases from being transmitted therethrough such as a metal foil laminate film storing the core. The inner bag comprises a depositing part and an air flow part and the externally enclosing material is formed by depressurizing the inside thereof for sealing deposition and bending the ear part of the external enclosing part including the deposit part along the end face of the core so that the convection space is not formed between the external enclosing material and the core. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
