PURPOSE:To provide a wire bonding method by which a wire can be welded properly and securely on the surface of electrodes for bonding even when the electrodes made of metal having high flatness on the surface thereof is used. CONSTITUTION:A pressing punch 10 is successively brought into contact with respective surfaces of electrodes 6 arranged on an electrode forming part in order to form recessed parts on the surface of the electrodes 6, and then a wire 7 passing through a capillary 12 is successively pressed on the surfaces of the electrodes 6 and the wire 7 is welded and bonded on the electrodes 6 through ultrasonic vibration. |
