Vacuum heat insulator comprising a laminated core made of a plurality of sheets of inorganic fibers having 10 μm or smaller in diameter and a certain composition including SiO2 as a main component, Al2O3, CaO, and MgO, a gas barrier enveloping member, and an absorbent. The vacuum heat insulator is characterized by having at least one groove formed therein after fabrication of the vacuum heat insulator. Further, the vacuum heat insulator is characterized by using inorganic fiber core of which a peak of distribution in fiber diameter lies between 1 μm or s...
1. A vacuum heat insulator comprising:a laminated core comprising a plurality of sheet-formed inorganic fibers; an enveloping member; and an absorbent, wherein said inorganic fibers include 50-65 wt % of SiO2, 10-20 wt % of Al2O3, 10-20 wt % of CaO, and 1-4 wt % of MgO, a fiber diameter of said inorganic fibers is 1 μm or larger and 5 μm or smaller, and a bulk density of said inorganic fibers is 100 Kg/m3 or more and 300 Kg/M3 or less. 2. The vacuum heat insulator according to claim 1, wherein said sheet-formed inorganic fibers are provided with a cut-of...
