Zusammenfassung:A radial type ultrasound transducer is arranged in an ultrasound endoscope including a bending portion on a distal end side of an insertion portion. The ultrasound transducer includes: a plurality of piezoelectric elements arranged at predetermined intervals in a circumferential manner and configured to transmit and receive ultrasound waves; a plurality of electrodes arranged in the respective piezoelectric elements; and a flexible printed circuit electrically connected to each of the electrodes. The flexible printed circuit includes a plurality of wires that extend such that at least parts of the wires cross a direction perpendicular to an arrangement direction of the piezoelectric elements, and the plurality of wires are electrically connected to the respective electrodes of the piezoelectric elements at positions where at least parts of the wires cross the direction perpendicular to the arrangement direction of the piezoelectric elements.
