Abstract: An ultrasonic endoscope includes a plurality of ultrasonic vibrators; a distal end part that houses the plurality of ultrasonic vibrators; an electrically conductive endoscopic structure housed in or connected to the distal end part; a thermally conductive member connected to the plurality of ultrasonic vibrators; and an electrically insulating thermally conductive member connected to the endoscopic structure. The thermally conductive member and the electrically insulating thermally conductive member are connected to each other. Thus, the ultrasonic endoscope that has a heat release structure which transmits the heat generated from the ultrasonic vibrators to the electrically conductive endoscopic structure housed in the distal end part and which can efficiently release the heat therefrom while electric safety is secured; and that can prevent a burn of an alimentary canal by suppressing a temperature rise of surfaces of the ultrasonic vibrators is provided.

Abstract: A ultrasonic-oscillator unit including an ultrasonic-oscillator array in which a plurality of ultrasonic-oscillators are arranged in a semicylindrical shape; an electrode part of the ultrasonic-oscillator array provided on an end surface of the ultrasonic-oscillator array perpendicular to an arrangement surface of the plurality of ultrasonic-oscillators; and a backing material layer that is disposed on an inner back surface of the ultrasonic-oscillator array; and a cable wiring part in which a plurality of cables are respectively disposed on a plurality of wiring lines electrically connected to the plurality of electrodes of the electrode part. The width of the backing material layer perpendicular to the arrangement surface of the plurality of ultrasonic-oscillators becomes smaller toward a side opposite to the arrangement surface of the plurality of ultrasonic-oscillators. A cable wiring part electrically connected to the electrode part is provided along the width of the backing material layer.
