<p><P>PROBLEM TO BE SOLVED: To provide a vacuum thermal insulation material usable in a high temperature area of 100 to 500°C, and capable of surely adhering a joining part. <P>SOLUTION: This vacuum thermal insulation material 10 is provided by putting the inside of an external facing material in a vacuum state, by joining the joining part 2, after exhausting the inside in a vacuum, by wrapping a filler 3 of laminating an inorganic fiber sheet and stainless foil and a getter material 4 by the external facing material composed of a stainless sheet 1 having the thickness of 0.02 mm to 0.05 mm. The joining part 2 is formed by arranging an Ag/Cu-based brazing material 5 having the thickness of 0.01 to 0.1 mm between an electrolytic nickel plating layer 6, by applying the electrolytic nickel plating layer 6 having the thickness of 3μm or more to an interface surface of the opposed stainless sheets 1. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
