A radiation heat transfer suppressor for inhibiting heat transfer by infrared rays is provided on the external surface of the enveloping member of a vacuum heat insulator. In heat-blocking or keep warm using a vacuum heat insulator, a surface having a radiation heat transfer suppressor is faced to a high-temperature side. Thus, the vacuum heat insulator exhibits excellent heat-insulating performance in a temperature range of 150�� C. or higher.
The invention claimed is: 1. A vacuum heat insulator comprising: a core; a gas-barrier enveloping member covering the core and having a depressurized inside; and a radiation heat transfer suppressor provided on at least one surface among external surfaces of the enveloping member, wherein the radiation heat transfer suppressor has a first inorganic material film, and a second inorganic material film having a reflectance different from that of the first inorganic material film, and the first inorganic material film and the second inorganic material film ...
