An actuator unit for a fuel injection valve of a vehicle internal combustion engine. The actuator unit includes an electronic component formed as a stack. The component includes a plurality of electrode layers and a plurality of material layers which are arranged alternately and react to the application of an electric field. The component also has two outer electrodes electrically connected to respective electrode layers on at least one circumferential side of the component. Additionally, the actuator unit has a piezoelectric sensor coupled to the component in a force-fitting manner, in the stroke direction of the component. When the component is in operation, the sensor detects a force generated by the component, as a voltage or charge between two electrodes arranged on opposing end faces, of a sensor element. The electrodes are deposited from an electrically conductive material directly onto at least the end faces of the sensor element.
