Abstract
The present invention discloses an ultrasonic oscillator including: a plurality of resonators; and an electricity-to-mechanical energy conversion element disposed among a plurality of the resonators and pressed by a fastening member, wherein the ultrasonic oscillator bends and/or oscillates when alternating voltage is applied to the electricity-to-mechanical energy conversion element, and the resonators do not come in contact with the fastening member in a portion adjacent to the end surface of the ultrasonic oscillator.
