PROBLEM TO BE SOLVED: To provide a coating film having high mold release characteristics and durability. SOLUTION: This coating method comprises the steps of: injecting chromium into the surface of objects to be film-formed 4a and 4b to form a chromium film thereon; injecting platinum ions into the surface of the chromium film; forming a platinum thin film on the surface; and injecting platinum ions into the surface. The method of injecting the chromium ion or the platinum ion comprises the steps of: making injecting devices 32<SB>1</SB>and 32<SB>2</SB>generate a trigger electric discharge therein by a trigger voltage to induce an arc discharge; consequently making a cathode emit the chromium ions and the platinum ions; and simultaneously applying a negative bias voltage of a pulse form to the object to be film-formed 4a and 4b, so as to synchronize with the arc discharge. Then, adhesiveness between an injected layer and a thin film is improved. COPYRIGHT: (C)2008,JPO&INPIT
