An ultrasonic transducer, an ultrasonic array, an ultrasonic module, an ultrasonic probe, and an ultrasonic device having high transmission output and reception sensitivity are provided. An ultrasonic transducer includes a flexible film and a piezoelectric element provided on the flexible film. The piezoelectric element includes a piezoelectric body, a first electrode in contact with the piezoelectric body, a second electrode, and a third electrode. The first electrode and the second electrode, the first electrode and the second electrode are spaced apart by sandwiching the piezoelectric body between the first electrode and the second electrode, and from the thickness direction of the piezoelectric body 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 the first electrode and the third electrode are overlapped in the plan view. Is separated in a plan view, and the second electrode and the fourth electrode are separated in a plan view. [Selection] Figure 6 |
