Piezoelectric transducer adapted to bridge of stringed instrument

A bridge for a stringed instrument equipped with a piezoelectric transducer for producing electric signals upon detection of vibrations of strings, said bridge comprising:

• a support member for supporting strings of the stringed instrument;
• and
• a bridge base for vertically supporting the support member,
• wherein said piezoelectric transducer comprises
• a piezoelectric element roughly having an elongated rectangular shape,
• a pair of electrodes that are respectively attached to an upper surface and a lower surface of the piezoelectric element,
• a pair of insulation members for insulating the pair of electrodes respectively,
• a shield layer that is arranged to cover the piezoelectric element, the pair of electrodes, and the pair of insulation members, and
• a thin metal plate that is adhered to at least an exterior of an upper surface of the shield layer and that is composed of a prescribed metal, which is selected from among copper, gold, and platinum, or a prescribed alloy mainly composed of one of copper, gold, and platinum.
