ABSTRACT:
An ultrasonic horn that has a capillary attachment hole to hold a capillary therein so as to be used in wire bonding, including a perpendicular slit provided on the opposite side of the capillary attachment hole from the tip end of the ultrasonic horn. An area surrounding the capillary attachment hole is formed thin, and the slit is narrowed and tightened by a bolt so as to insure a stable capillary holding force and prevent deterioration in the holding force over time.
