PROBLEM TO BE SOLVED: To provide an ultrasonic transducer having high transmission output and reception sensitivity, and an ultrasonic array, an ultrasonic module, an ultrasonic probe and an ultrasonic device.SOLUTION: The ultrasonic transducer comprises a flexible film and a piezoelectric element provided on the flexible film. The piezoelectric element has a piezoelectric material, a first electrode, a second electrode, a third electrode and a fourth electrode which are in contact with the piezoelectric material,. The first electrode and the second electrode are separated from each other with the piezoelectric material interposed between the first electrode and the second electrode, and overlap with each other in a plan view viewed in a thickness direction of the piezoelectric material. The third electrode and the fourth electrode are separated from each other with the piezoelectric material interposed between the third electrode and the fourth electrode, and overlap with 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.SELECTED DRAWING: Figure 6【課題】高い送信出力及び受信感度を有する超音波トランスデューサー、超音波アレイ、超音波モジュール、超音波プローブ、及び超音波装置を提供する。【解決手段】超音波トランスデューサーは、可撓膜と、可撓膜に設けられる圧電素子と、を備え、圧電素子は、圧電体と、圧電体に接する第一電極、第二電極、第三電極、及び第四電極と、を有し、第一電極と第二電極とは、第一電極と第二電極との間に圧電体を挟んで離間し、かつ、圧電体の厚さ方向から見た平面視において重なり、第三電極と第四電極とは、第三電極と第四電極との間に圧電体を挟んで離間し、かつ、平面視において重なり、第一電極と第三電極とは、平面視において離間し、第二電極と第四電極とは、平面視において離間する。【選択図】図６
