Zusammenfassung:	PURPOSE:To obtain a titled composite body free from a cracking defect in the stage of coating the periphery of a ceramic core material with an iron-base alloy by subjecting the ceramic core material to insert-casting by the iron-base alloy having specific tensile strength in a prescribed temp. region. CONSTITUTION:The iron-base alloy having 20-70kgf/mm. tensile strength from an ordinary temp. up to 400 deg.C is selected and is used for insert-casting of the prescribed ceramic core material in the stage of producing a composite ceramic- iron-base alloy body by insert-casting of the iron-base alloy to the periphery of the ceramic core material. The composite ceramic-iron-base alloy body which is free from a crack and breakage in both of the core material and the alloy layer is thus obtd.
