PURPOSE:To obtain a ceramic-metal composite body while preventing the crack of a member consisting of ceramics in the stage of cooling by embedding the member consisting of ceramics by casting of a molten metallic material dispersed therein with ceramic particles. CONSTITUTION:The member consisting of ceramics (e.g.; Al2O3 member) is embedded by casting of the molten metallic (e.g.; JIS heat resisting cast steel SCH12) material dispersed therein with the ceramic (e.g.; Al2O3) particles by which the intended ceramic-metal composite body is obtd. The above-mentioned ceramic particles are preferably incorporated at 0.5-60vol% into the metallic material. The average grain size of the ceramic particles is preferably about 0.01mum-1.0mm. The ceramic-metallic composite body obtd. by the above- mentioned method is usable up to the higher temp.
