Abstract
The present invention includes: an ultrasonic horn () to which two ultrasonic vibrations can be input to excite a capillary () mounted to a front end with different frequencies in a Y-direction and an X-direction; and a control unit () which adjusts the respective magnitude of the two ultrasonic vibrations. The Y-direction is a direction in which the ultrasonic horn () extends. The control unit () adjusts the respective magnitude of the two ultrasonic vibrations to adjust a ratio (ΔY/ΔX) of amplitude of the capillary () in the Y-direction and the X-direction. Thus, degradation in the quality of the joining between wires and leads is suppressed.
