1. An ultrasonic endoscope comprising:
a distal end portion main body that is provided at a distal end of an insertion part and has a cable insertion hole therein;
a storing portion that is provided in the distal end portion main body and is formed on a distal end side in an axial direction of the distal end portion main body from the cable insertion hole;
an ultrasonic transducer that is disposed in the storing portion and has a plurality of ultrasonic vibrators;
an elevator housing portion that is provided in the distal end portion main body and is open in a first direction orthogonal to the axial direction of the distal end portion main body;
an elevator that is provided in the elevator housing portion;
a plurality of signal cables that are connected to the plurality of ultrasonic vibrators, respectively; and
a cable introducing portion, communicating with the storing portion and the cable insertion hole, and introduces the plurality of signal cables to the cable insertion hole,
wherein the storing portion is disposed at a position offset in a second direction, which is orthogonal to the axial direction of the distal end portion main body and is orthogonal to the first direction, from a position where the cable insertion hole is provided,
an inner wall surface of the cable introducing portion has a guiding surface communicating with the cable insertion hole, in which a width of the guiding surface in the second direction increases from the storing portion toward a proximal end side in the axial direction of the distal end portion main body.
