Abstract
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 SiOas a main component, AlO, 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 smaller and 0.1 μm or larger, and not containing binding material for binding the fiber material. Electronic apparatuses use the vacuum heat insulator. With use of the vacuum heat insulator, electronic and electric apparatuses superior in energy saving and not to present uncomfortable feeling to the user can be provided.
