Beschreibung
Zusammenfassung:	There are provided an ultrasonic treatment tool and an endoscope system with which it is possible to improve an efficiency of transmitting ultrasonic vibration to a structure such as a blood vessel and absorbing the ultrasonic vibration by the structure, and to suppress a temperature rise of a device by increasing an efficiency of conversion into ultrasonic vibration with respect to supplied power.An ultrasonic treatment tool (18) includes a grip part (33) that grips a structure in a subject; and an ultrasound oscillator unit (34) that is provided in the grip part (33) and disposed at a position facing the gripped structure. A piezoelectric material constituting the ultrasonic vibration unit (34) has a mechanical quality coefficient of 500 or more.
