<p>The present invention relates to the field of piezo transducer technologies, and provides an electrode of a piezo film ultrasonic transducer having a piezo film. The piezo film includes a working portion and a lead-out portion. The electrode of a piezo film ultrasonic transducer includes: a first base plated electrode layer that is plated on a same surface of the working portion and the lead-out portion of the piezo film; a first conductive layer coated on the other surface of the first base plated electrode layer; and a second base plated electrode layer plated on the other surface of the working portion and the lead-out portion. After a base electrode layer is plated on a surface of the lead-out portion and the working portion of the piezo film, a conductive layer is coated on the other surface of the electrode layer. Therefore, when the conductive layer is coated to a region of the electrode layer that is on the lead-out portion, the reliability of connections between electrodes on the surface of the lead-out portion and electrodes of a PCB can be improved.</p> |
