Abstract
Vacuum insulator includes core member and jacket which covers core member. Jacket is decompressed its interior and core member includes a glass-fiber laminated unit. The glass fiber is formed of toughened glass-fiber which is low brittle and its fiber strength is toughened. This structure allows improving the heat insulating performance as well as lowering the material cost of vacuum insulator.
