<p>Disclosed is a piezoelectric actuator, e. g. for actuating a mechanical part, which allows reciprocal lateral contact between inner electrodes (3, 4: 10, 13) and outer electrodes (9: 19, 20) by means of a multilayer structure comprising piezoelectric layers (2) and intermediate inner electrodes (3, 4;10, 13). The individual inner electrodes (10, 13) are rounded at the corners (11) formed by the cutting edges before being integrated into the multilayer structure. The corners of chamfers can also be rounded if the corners (11) are provided with a chamfer (16).</p> |
