[0120] Figure 15 It is a plan view showing the upper surface of a printed circuit board on which signal lines corresponding to a plurality of ultrasonic vibrators are arranged in an ultrasonic endoscope including an ultrasonic probe according to a third embodiment of the present invention.
[0121] Such as Figure 15 As shown, the ultrasonic vibrator printed circuit board 301 in the third embodiment has the same function as the ultrasonic vibrator printed circuit board 101 in the first embodiment in that a signal pattern from the ultrasonic vibrator is arranged. However, unlike the first embodiment, the third embodiment is characterized in that a plurality of signal pattern groups are separated and bent on both sides of the circuit board, and that the pad electrode portion at the front end is also placed on the circuit board. The two sides are separated and arranged along the longitudinal axis direction, and both pass through the direction changing circuit board, thereby cha...
