摘要： An ultrasonic endoscope, comprising an ultrasonic probe formed by arranging a plurality of ultrasonic vibrator elements transmitting/receiving ultrasonic wave in a roughly cylindrical shape, a tip hard part forming the tip of an endoscope insertion part and having the ultrasonic probe thereat, a curved tube part connected to the tip hard part and curved by remote control, a flexible tube part connected to the curved tube part, and a signal line bundle for the ultrasonic vibrator elements to transmit drive signals for driving the ultrasonic vibrator elements and passed through the insides of the tip hard part, the curved tube part, and the flexible tube part. The signal line bundle is covered by an arresting member arresting the signal line bundle, and is characterized in that the arresting force of the arresting member covering the signal line bundle in the prescribed area of the signal line bundle enclosed in the curved tube part is smaller than that of the arresting member covering those areas of the signal line bundle other than that area.
