Multilayer piezoelectric actuator device having a conductive member attached to an external electrode thereof

摘要

In a multilayer piezoelectric actuator device having a plurality of piezoelectric elements (1a) and a plurality of internal electrodes (1b) stacked in a stacking direction to form a multilayer structure (1) so that each of the internal electrodes is placed between adjacent ones of the internal electrodes. A pair of external electrodes (2) are disposed on a side surface of the multilayer structure and connected to adjacent ones of the internal electrodes, respectively. A pair of conductive members (3) are connected to the external electrodes, respectively. Each of the conductive member is spaced from and faced to the side surface of the multilayer structure.
