In the ultrasound transducer of the present embodiment, front surface electrodes and rear surface electrodes are provided for a plurality of ultrasound vibrators. A circuit board is disposed on the rear surface side of the ultrasound vibrators, and connected to the rear surface electrodes. An electronic circuit is connected to the surface opposite to that of the rear surface electrodes side on the circuit board, and has signal paths to each ultrasound vibrator through the circuit board. A backing material is disposed on the rear surface side of the ultrasound vibrators, and is provided so as to sandwich between it and the ultrasound vibrators the circuit board and the electronic circuit. |
