Disclosed is a coating of a hard carbon film having higher adhesion strength on metal members such as dies, cutting tools, and machine parts such as a stainless steel material to which a diamond-like carbon film is difficult to adhere firmly. [Structure] In a metal member coated with a diamond-like carbon (DLC) film, amorphous iron silicide is on the metal member side, and Si, silicon oxide, BCN compound, or a compound of the compound and Si is an intermediate layer on the DLC film side A metal member coated with a diamond-like carbon film characterized by interposing as follows.
