1. An ultrasound endoscope distal end portion comprising:
an ultrasound transducer that is provided at a distal end of an insertion portion and has an ultrasound transmission/reception surface that transmits/receives ultrasound and a back surface positioned on a side opposite to the ultrasound transmission/reception surface; a wiring substrate that is arranged on the back surface and is electrically connected to the ultrasound transducer; a plurality of wires that include a bending portion that is connected to the wiring substrate from an upward direction which is a direction toward the ultrasound transmission/reception surface viewed from the wiring substrate to a backward direction which is a direction opposite to the upward direction and thereafter bent toward a direction different from an insertion axis which is a direction in which the insertion portion is inserted; a restricting section that is disposed so as to cover the wiring substrate and is made of a non-conductive material; a wiring substrate side fitting section that is provided on the wiring substrate and fits with the restricting section; and a first restricting section side fitting section that is provided in the restricting section and fits with the wiring substrate.
