摘要：An ultrasonic transducer includes a plate-shaped piezoelectric body consistingof a piezoelectric polymer material and having a polarized portion obtained by polarizinga prescribed region thereof, as well as first and second unpolarized portions contiguousto the polarized portion. A first electrode is formed on one main surface of thepiezoelectric body to cover the polarized portion and has an edge portion extendingover the first unpolarized portion. A second electrode is formed on the other mainsurface of the piezoelectric body to cover the polarized portion and has an edge portionextending over the second unpolarized portion. A first conductive lead is electricallyconnected to the edge portion of the first electrode, and a second conductive lead iselectrically connected to the edge portion of the second electrode.
