1. A treatment device for use in treating a biological tissue, comprising:

  • a holding portion to be held by a user;

    an ultrasonic transducer unit that generates an ultrasonic vibration in accordance with a supply of a power;

    a probe which defines a longitudinal axis, is configured to transmit the ultrasonic vibration generated by the ultrasonic transducer unit, and has a treatment portion configured to treat the biological tissue by an action of the ultrasonic vibration transmitted to a distal end portion of the probe;

    an inner sheath that covers an outer peripheral surface of the probe;

    a first sealing member that is interposed between an inner peripheral surface of the inner sheath and the outer peripheral surface of the probe, and comes in contact closely with the inner peripheral surface of the inner sheath and the outer peripheral surface of the probe to prevent penetration of a liquid;

    an outer sheath that covers an outer peripheral surface of the inner sheath;

    a second sealing member that is interposed between the outer peripheral surface of the inner sheath and an inner peripheral surface of the outer sheath, and comes in contact closely with the outer peripheral surface of the inner sheath and the inner peripheral surface of the outer sheath to prevent the penetration of the liquid; and
