An actuator device and a manufacturing method for the actuator device with which an outer electrode electrically connected to an inner electrode can be reliably formed even when using a film made of an electrostrictive material. An actuator device includes a plurality of stacked electrostrictive films each of which is made of an electrostrictive material and includes inner electrodes formed on one surface or both surfaces of the film. Lead electrodes are formed to be led out respectively from the inner electrodes toward the outside of the electrostrictive film 31. At least one cut portion is formed in each of the lead electrodes, and conductive ink is applied to the cut portion. The conductive ink reaches, from the cut portions, the lead electrodes formed on the electrostrictive film.
