Zusammenfassung:PROBLEM TO BE SOLVED: To improve productivity and to decrease cost by preparing a composite material by filling and impregnating pores of a porous ceramic body with a metal to have a specified or lower bulk density, less than a specified volume resistivity, a specified or smaller coefft. of thermal expansion and a specified or higher Young's modulus. SOLUTION: The composite material used has 6.0 or smaller bulk density, less than 107 Ω.cm volume resistivity,
