Kind Code:
B2
Abstract:
There is provided an ultrasonic endoscope, in which bending of a signal cable at a time of assembling a distal end portion is alleviated and the signal cable is prevented from being disconnected, and a manufacturing method thereof. An ultrasonic endoscope (1) includes a cable insertion hole (88), a storing portion (90) that is formed on a distal end side of the cable insertion hole (88), an ultrasonic transducer (50) that has an ultrasonic vibrator disposed in the storing portion (90), an elevator housing portion (62) that is open in a first direction, an elevator (60), and a distal end portion main body (36) that has a signal cable (86) connected to the ultrasonic vibrator, in which the storing portion (90) is disposed at a position offset in a second direction orthogonal to a first direction from a position where the cable insertion hole (88) is provided, the storing portion (90) has a cable introducing portion (92) that introduces the signal cable (86) into the cable insertion hole (88), and the cable introducing portion (92) has a guiding surface (94) in which a width of the storing portion (90) in the second direction gradually increases toward a proximal end side, and a manufacturing method thereof.
