ABSTRACT:
A vacuum heat insulator is provided which includes a vacuum heat-insulated space defined between a pair of spaced outer skin members, a portion of the space closer to one of the outer skin members being set as high-temperature side, with a portion closer to the other outer skin member being set as low-temperature side. A laminate is disposed at the high-temperature side of the vacuum heat-insulated space, and a board having an inorganic material is disposed at the low temperature side. The laminate includes inorganic sheet members and metallic foils with low heat emissivity, the sheet members and metallic foils being alternately laid in plural layers.
