Abstract

An ultrasonic transducer array (10) comprises: a plurality of units (20) each of which includes a piezoelectric element (21) and a vibration plate (22); a first electricity conducting path (30) electrically connected to each of the vibration plates (22) of the plurality of units (20); and a second electricity conducting path (40) electrically connected to each of electrodes (27) provided on second main faces (25) of the piezoelectric elements (21) of the plurality of units (20). The first electricity conducting path (30) includes an electricity conducting member (32) disposed on a side opposite the vibration plates (22) with the piezoelectric elements (21) intervening therebetween, and a plurality of first spring members (31) individually disposed between each of the plurality of vibration plates (22) and the electricity conducting member (32). A first end (31A) of each of the plurality of first spring members (31) is in contact with a corresponding one of the plurality of vibration plates (22), and a second end (31B) of each of the plurality of first spring members (31) is in contact with the electricity conducting member (32) in common.
