| PROBLEM TO BE SOLVED: To obtain a high adhesive strength with a simple composition even when a substrate of hyperfine-grained high cemented carbide alloy with a large content of Co is coated with a diamond film. SOLUTION: The surface of substrate 12 of hyperfine-grained high cemented carbide alloy with a large content of Co is subjected to roughening treatment to the prescribed surface roughness, thereafter, an intermediate layer 18 of TiAlN is formed by a PVD method without performing removal treatment of Co by means of acid treatment, etc., and the diamond film 16 is applied on the intermediate layer 18 by using a microwave plasma CVD device. | ||||||
