Abstract
In order to provide a light heat insulating member having both an extremely low thermal conductivity and a high heat resistance in an atmosphere, in which pressure is reduced, a core member consisting of accumulated heat resisting inorganic fiber is put between a high temperature side skin member and a low temperature side skin member made of heat resisting fiber textile and these three members are tied all together in one body by sewing, using heat resisting inorganic fiber thread. It is possible to reduce the thermal conductivity to an extremely small value by adding a material having a high emissivity (SiC powder, SiC whisker) to the core member and to prevent scattering of material constructing the core member by covering side wall parts of the core member by the high temperature skin member.
