Abstract
An ultrasound treatment tool includes: a vibration transmitter configured to transmit ultrasound vibration from a proximal end toward a distal end; a tube into which the vibration transmitter is inserted; a rigid part that is made of a resin material that is harder than the tube, the rigid part being provided on an outer peripheral surface of the vibration transmitter at a node position of the ultrasound vibration, the rigid part being in contact with an inner peripheral surface of the tube; and a pipe configured to cover an outer peripheral surface of the tube. The tube is expanded by the rigid part to be in contact with an inner peripheral surface of the pipe.
