ABSTRACT:
In a direction parallel to a direction5of ultrasonic vibrations imparted from an ultrasonic vibrator1, the shape of a center portion3aof a tool3and the shape of an end portion3bof the tool3are changed such that the cross-sectional areas are different, whereby ultrasonic amplitudes9in a direction perpendicular to the direction5of ultrasonic vibrations are substantially equal. By this means, the difference in ultrasonic vibration between at the center portion3aof the tool3and at the end portion3bof the tool3can be eliminated or reduced.
