1. An ultrasonic endoscope comprising:
an ultrasonic transducer that has an ultrasonic vibrator;
a distal end portion body that is disposed continuously with a proximal end side of the ultrasonic transducer;
an erecting base housing portion that is disposed in the distal end portion body and that has an opening whose opening direction is one side in a first direction that is perpendicular to an axial direction of the distal end portion body or whose opening direction is a direction that has a component toward one side in the first direction and a component toward a distal end side in the axial direction of the distal end portion body;
a treatment tool lead-out port that communicates with an inside of the erecting base housing portion and from which a treatment tool is led out;
an erecting base that is disposed in the inside of the erecting base housing portion and that changes a lead out direction of the treatment tool led out from the treatment tool lead-out port; and
a cleaning communication hole that is formed in a wall surface on a side opposite to a side where the opening of the erecting base housing portion is disposed and that communicates with an outside,
wherein the ultrasonic endoscope has a signal cable that is connected to the ultrasonic vibrator,
wherein, in a case where the signal cable and the erecting base housing portion are projected onto a plane that is perpendicular to the first direction, the signal cable is disposed in a region that is different from a region where the erecting base housing portion is disposed.
