An ultrasonic transducer device includes a substrate, an ultrasonic element array having a plurality of ultrasonic element rows each including a plurality of ultrasonic elements arranged along a first direction and electrically connected to each other, the plurality of ultrasonic element rows being arranged along a second direction intersecting with the first direction, and a plurality of common electrode wirings each configured to independently supply a common voltage to at least one of the ultrasonic element rows, the common electrode wirings extending along the first direction, one of the common electrode wirings being arranged between a pair of the ultrasonic element rows with respect to the second direction, the common electrode wirings being non-overlapped with the ultrasonic elements as viewed in a thickness direction of the substrate that is a normal direction of a surface of the substrate over which the ultrasonic element array is disposed.
