An ultrasound endoscope, having a cable for connecting the ultrasound endoscope to a driving apparatus, includes an insertion section insertable into a subject, a plurality of transducers provided at a distal end portion, an electrode formed in each of the transducers, a wiring section connected to the electrode to electrically connect the electrode and the cable, and matching circuits, at least one of which is provided at an end of or partway in each of the wiring section. The electrode, the wiring section, and the matching circuits are provided in each of the plurality of transducers. The cable includes a core wire and an insulating layer enwrapping the core wire and functions as a matching section that matches electric impedance of each of the transducers between the plurality of transducers and the driving apparatus by varying a thickness or quality of material of the insulating layer.
