Abstract
The present invention relates to a piezoelectric driving devicecapable of moving the movable memberalong the axis direction engaged in a movable manner to the axial direction with respect to the shaft. A pair of the external electrodesandrespectively comprises the first external connection partand the second external connection partformed at the lower end face in Z axis direction by being insulated against each other. At the opposing face of the weight memberfacing against the lower end face of the element, the first circuit patternand the second circuit patternare formed by being insulated against each other; and the first circuit patternand the second circuit patternare respectively connected to the first external connection partand the second external connection partby a metal bonding.
