    • PROBLEM TO BE SOLVED: To improve a frame rate in an electronic radial scanning in an ultrasonic endoscope capable of imaging an ultrasonic tomogram by inserting the ultrasonic endoscope in the body of a patient. SOLUTION: The ultrasonic endoscope is equipped with an ultrasonic transducer part including a plurality of ultrasonic transducers T1-T360 each of which has first and second electrodes and transmits and receives ultrasound, a plurality of first wirings EL1-EL180 respectively connected to the first electrodes of the plurality of ultrasonic transducers, and a plurality of second wirings G1, G2 respectively connected to the second electrodes of the plurality of ultrasonic transducers with the first electrodes which are not connected mutually. When driving signals are selectively supplied to the ultrasonic transducer part through the plurality of the first wirings and the plurality of the second wirings, the ultrasonic transducer part performs scanning by simultaneously transmitting the same number of ultrasonic beams in respective region AR1-AR4 at a constant angular space.
