PROBLEM TO BE SOLVED: To provide a heat insulating molding in which a heat insulating material has so low water absorbing potential as to be able to dissolve a problem of steam. SOLUTION: The heat insulating molding is made of molded and/or sintered heat insulating material and contains fume silica, an inorganic filler, an opaquer and fiber. The heat insulating material has BET specific surface area of <100 m<2> /g, between 10 m<2> /g and 100 m<2> /g, for example, and consequently the heat insulating molding absorbs little water. In the case of a radiating heater, the heat insulating molding is used as a base part of a heating resistor. |
