Abstract: An ultrasonic horn includes: a vertical vibration generating portion in which a first ultrasonic vibrator is mounted inside; a horn portion extending forward from the vertical vibration generating portion , amplifying an ultrasonic vibration generated by the vertical vibration generating portion , and to which a capillary is mounted at a front end portion ; and a torsional vibration generating portion extending rearward from the vertical vibration generating portion . The torsional vibration generating portion includes: a rod-shaped body ; vibration members arranged axisymmetrically around a central axis ; second ultrasonic vibrators sandwiched between the rod-shaped body and the vibration members such that a vibration direction is a circumferential direction; and bolts pressurizing the second ultrasonic vibrators.
