Piezoelectric driving device

摘要

To provide a piezoelectric driving device in which a short circuit does not occur between electrode metallic films even if performing bonding-wire joining, the piezoelectric driving device is a piezoelectric driving device in which a piezoelectric thin plate is joined to one side of a substrate and a terminal electrode for applying a signal for expanding or contracting the piezoelectric thin plate is further formed on the plane and the terminal electrode is formed on one side of the substrate through a piezoelectric-member pedestal separated from the piezoelectric thin plate.
