Реферат: The invention relates to a piezo actuator (1) comprising a multi-layer structure consisting of piezo layers and of inner electrodes (2, 3) placed therebetween, and comprising a mutual lateral contacting of the inner electrodes (2, 3) via outer electrodes (4), via which an electric voltage can be supplied. According to the invention, the outer electrodes (4) are contacted at least at points by the respective inner electrodes (2, 3) and a stretchable area can lie between the contactings. The outer electrodes (4) are each comprised of a shaped part (5) and of individual wires (6). These individual wires (6), while running parallel to the layers, are contacted by the respective inner electrodes (2, 3), and the individual wires (6) form a zone that can undergo stretching between the contacting and the shaped part (5) and/or areas of the shaped part (5).
