A piezo actuator is disclosed, for example for operation of a mechanical component, in which a multi-layered construction of piezo layers (2), with inner electrodes (3, 4) arranged therebetween is provided. An alternate connection of the inner electrodes (3,4) with outer electrodes (5,6) is provided, whereby the regions between the outer electrodes (5,6) have a suitable insulation (7,8). The insulation is a layer made from an strip, preferably an adhesive strip (7, 8), which covers a pre-determined region between the outer electrodes (5, 6). The adhesive strip (7,8) comprises a ready-made material of precise dimensions which can be stuck on without air-bubbles, rolled, fused, vulcanized or sintered.
