Abstract
A distal hard part in an insertion portion is provided with an ultrasonic transducer in which a large number of ultrasonic vibrators are arranged in the circumferential direction. The ultrasonic transducer is shaped like a cylinder. Each member that constitutes an endoscopic observation section is passed through this tunnel-like passage. Each ultrasonic vibrator is provided with a single common electrode and individual electrodes the number of which corresponds to the number of the ultrasonic vibrators. Flexible boards and are provided on the proximal and distal end sides of the ultrasonic transducer. Wires are connected to these flexible boards. The wires from the flexible board are extended without changes, whereas the wires from the flexible board are reversely turned from the distal end side, are then passed through the tunnel-like passage, and are extended in the direction of an angle part.
