Zusammenfassung:	PURPOSE:To produce a formed body having satisfactory cutting quality and excellent in corrosion resistance by forming a diamondlike carbon film on a metallic substrate and fluorinating the surface of the carbon film. CONSTITUTION:Gaseous starting material contg. carbon and hydrogen is excited with plasma and brought into contact with the surface of a metallic substrate 7 to form a diamondlike carbon film and starting material contg. fluorine is excited with plasma and brought into contact with the surface of the diamondlike carbon film to form a fluorinated layer 18.
