The invention relates to an actuator (1), comprising: piezoelectric elements (16) arranged in a stack; first and second inner electrodes (5, 3), which are alternately arranged between the piezoelectric elements (16); a first outer electrode (4), which is connected to the first inner electrodes (5) in an electrically conductive manner; a second outer electrode (2), which is connected to the second inner electrodes (3) in an electrically conductive manner. The actuator (1) is characterized in that the actuator (1) comprises a plurality of actuator sections (81, 82, 83, 84, 85), and the second outer electrode (2) comprises separate electrode segments (21, 22, 23), which are each connected in an electrically conductive manner to the second inner electrodes (3) in one of the actuator sections (81, 82, 83, 84, 85) or in a group of the actuator sections (81, 82, 83, 84, 85).
