Abstract: An ultrasonic treatment apparatus includes a movement unit moving in accordance with at least one of an acting state of a load to a treatment section from a jaw and an opening angle of the jaw relative to the treatment section, a movement detector detecting a moving state of the movement unit, and a peak detecting section detecting a target peak of an ultrasonic impedance value. The ultrasonic treatment apparatus includes a control section controlling the peak detecting section to a detection disallowed state where a detection of the target peak is not executed when the movement unit is not placed within a prescribed range based on a detection result in the movement detector.
