ULTRASONIC TRANSDUCER AND METHOD OF MANUFACTURING SAME |
摘要 |
An ultrasonic transducer includes a plate-shaped piezoelectric body made of a piezoelectric polymer material and having a polarized portion obtained by polarizing a prescribed region thereof, as well as first and second unpolarized portions contiguous to the polarized portion. A first electrode is formed on one main surface of the piezoelectric body to cover the polarized portion and has an edge portion extending over the first unpolarized portion. A second electrode is formed on the other main surface of the piezoelectric body to cover the polarized portion and has an edge portion extending over the second unpolarized portion. A first conductive lead is electrically connected to the edge portion of the first electrode, and a second conductive lead is electrically connected to the edge portion of the second electrode. |
