Disclosed are a composite material produced by arranging and forming, in an optional or specific form, composite portions including a plurality of protruding portions comprising at least silicon carbide and optionally metallic silicon and excellent in wear resistance and oxidation resistance on the surface of a C/C composite which is a composite carbon fiber or the surface of a molded product produced by molding the C/C composite in a desired shape depending on the use; and a composite material having substantially flattened surface on which at least composite portions are formed and which is obtained by cutting the protruding portions to nearly the same level as the surface of the sea. In this composite material, the low oxidation resistance of the C/C composite can be overcome and the material can be used at high temperatures and in the presence of oxygen. Furthermore, the material also has excellent wear resistance.
