Abstract: An ultrasonic treatment tool includes: an ultrasonic oscillator in which a plurality of piezoelectric elements configured to generate ultrasonic oscillation are arranged along a longitudinal axis direction of the ultrasonic oscillator, the ultrasonic oscillator being configured to transmit the ultrasonic oscillation from a proximal end side to a distal end side of the ultrasonic oscillator; a contact receiver configured to transmit power and a control signal to the ultrasonic oscillator; and a floating structure configured to suppress transmission of ultrasonic oscillation generated by the ultrasonic oscillator to the contact receiver or dampen the ultrasonic oscillation.
