Zusammenfassung:	To provide an ultrasonic welding method for conductors that is capable of suppressing occurrence of insufficient weld strength and a separation which may occur when terminals of a plurality of wires are ultrasonically welded. In a wire arranging step, a plurality of wires are arranged in accordance with a predetermined arrangement. In a conductor moving step, conductors (2) are pressed in a predetermined direction by a grinding jaw (12), and thereby relative positions among the conductors (2) are changed. In a first ultrasonic welding step, ultrasonic welding is performed on the conductors (2) in a state of being pressed by the grinding jaw (12). In a second ultrasonic welding step, the pressing applied by the grinding jaw (12) is released, and ultrasonic welding is performed on the conductors (2).
