1. An ultrasonic endoscope comprising:
an ultrasonic transducer including an ultrasonic wave transmission/reception surface configured to irradiate a subject with an ultrasonic wave and receive an ultrasonic echo reflected from the subject;
a cable including one end electrically connected to the ultrasonic transducer and another end electrically connected to a board connected to an ultrasonic observation device that transmits or receives a signal to or from the ultrasonic transducer;
a relay board configured to relay an electrical connection between the ultrasonic transducer and the one end of the cable; and
an exterior casing formed of a single type of resin having an insulation property, the casing having:
a first opening defining a cavity having at least first and second walls, the ultrasonic wave transmission/reception surface of the ultrasonic transducer is exposed from the opening and the relay board is disposed in the cavity, the cavity having:
the first wall on a proximal side of the casing, the first wall having a second opening through which the cable extends, and
the second wall opposing the first opening through the cavity, wherein the second wall directly abutting on at least a side surface of the relay board.
