PURPOSE: To obtain a carbon-silicon carbide-metal conjugate material having improved impermeability, mechanical strength, heat resistance and abrasion resistance by subjecting a surface layer of a specified section (sliding section) of a carbon base material to a silication treatment and further impregnating metal to the whole body of the carbon material. CONSTITUTION: This conjugate material is produced by the following processes: (A) a process for forming a carbon base material having an average fine pore semidiameter of >=0.5μm into a product shape; (B) a process for applying a slurry prepared by suspending metallic silicon powder in a solution containing at least one selected from a polyamide imide, a polyvinyl alcohol and a polyamide resin on a specified position of the processed base material; (C) a process for forming a partial silicate coat on the base material by drying and curing the coated base material, and further baking at >=1500 deg.C; and (D) a process for impregnating metal on the whole body of the carbon base material. A metal for the impregnation is preferably antimony, silver, tin, copper or an alloy containing at least one selected from these metals as a main component.
