<p>A piezoelectric actuator for a fuel injection valve has an actuator body with a multiplicity of ceramic layers and a multiplicity of electrode layers which are arranged between the ceramic layers. In this case, an external electrode is provided which is connected to some of the electrode layers. The external electrode has a plurality of longitudinal wires, which run in the longitudinal direction of the actuator body, and a plurality of weft wires, wherein a weft wire is passed through the longitudinal wires in such a way that some of the longitudinal wires run above the weft wire and other longitudinal wires run beneath the weft wire.</p> |
