Abstract
A piezoelectric actuator for actuating a mechanical component in which, with a multilayer construction of piezoelectric layers and inner electrodes disposed between them, an alternate-side lateral contacting of the inner electrodes with outer electrodes is possible. Before being put together to make the multilayer construction, the individual inner electrodes are rounded at the corners formed by the cut edges. The corners may each have a chamfer and the corners of the chamfers may each also be rounded.

1-4. (canceled)
In a piezoelectric actuator, comprising
- a multilayer construction of piezoelectric layers (2) having corners defined by cut edges and inner electrodes (3, 4;
- 10, 13) disposed between the piezoelectric layers, and
- an alternate-side lateral contacting of the inner electrodes (3, 4;
- 10, 13) with outer electrodes (9;
- 19, 20), the improvement wherein
- the individual inner electrodes (10, 13) are rounded at the corners (11) formed by the cut edges.
