ABSTRACT:
A piezoelectric transducer, adapted to a bridge of a stringed instrument such as a sound mute guitar, comprises a piezoelectric element roughly having an elongated rectangular shape, a pair of electrodes respectively attached to the upper and lower surfaces of the piezoelectric element, and insulation sheets for insulating the electrodes, all of which are covered with a conductive shield (e.g., a polymeric piezoelectric film), wherein a thin metal plate is adhered to at least the exterior of the upper surface of the conductive shield and is composed of a prescribed metal, which is selected from among copper, gold, and platinum, or a prescribed alloy mainly composed of one of these metals. The thin metal plate is adhered to the conductive shield by use of unhardened adhesive with a coating thickness of 10 μm or less.
