    Abstract: An ultrasonic transducer device includes an ultrasonic transducer element array, a first signal terminal, and a second signal terminal. The ultrasonic transducer element array has a 1st element group to a kth element group (where k is a natural number such that k≧2). The first signal terminal is connected with a control section configured and arranged to perform at least one of receiving and transmitting of signals. The second signal terminal is connected with the first signal terminal via the ultrasonic transducer element array. Each of the 1st element group to the kth element group includes a plurality of ultrasonic transducer elements electrically connected in series. The 1st element group to the kth element group are electrically connected in parallel between the first signal terminal and the second signal terminal.

    Abstract: An ultrasonic transducer includes: a flexible film; and a piezoelectric element provided on the flexible film. The piezoelectric element includes a piezoelectric body and a first electrode, a second electrode, a third electrode, and a fourth electrode in contact with the piezoelectric body. The first electrode and the second electrode are separated from each other with the piezoelectric body interposed between the first electrode and the second electrode and overlapping each other in plan view. The third electrode and the fourth electrode are separated from each other with the piezoelectric body interposed between the third electrode and the fourth electrode and overlapping each other in the plan view. The first electrode and the third electrode are separated from each other in the plan view, and the second electrode and the fourth electrode are separated from each other in the plan view.

    Abstract: A piezoelectric element is provided with three electrodes, namely a first electrode, a second electrode, and a third electrode, arranged linearly on one side surface of a piezoelectric body at regular intervals. A polarization processing electric field is applied between the first electrode and the second electrode, and then the polarization processing electric field is applied between the second electrode and the third electrode. The polarization processing electrode field on this occasion is a half as strong as in the case of performing the polarization process of applying the electric field at a time between the first electrode and the third electrode.
