Abstract: The invention relates to a piezo actuator, for example, for actuating a mechanical component, in which a multilayer structure consisting of piezo layers (2) and inner electrodes (3, 4) arranged therebetween are provided. A mutual contacting of the inner electrodes (3, 4) with outer electrodes (5, 6) is provided, and the piezo actuator (1) has chamfered corners or edges (10). In the area of the corners or edges (10) on the sides of the piezo actuator (1), on which the inner electrodes (3, 4) are led with alternating polarity to the respective outer electrodes (5, 6), the inner electrodes (3) have a contour that enables the generation of a reduced field intensity between the inner electrodes (3, 4) of a different polarity in the structure consisting of the piezo layers (2). This is achieved by virtue of the fact that the edge (10) on the side, which is not contacted by the outer electrodes (5, 6), has an obtuse angle ( alpha ) or is rounded.
