Abstract: Proposed is a laterally multilayered dielectric elastomer actuator and a method of manufacturing the same. The actuator includes a polymer frame, an electrode, and a dielectric elastic portion. The polymer frame includes a first pattern with a first comb shape of a predetermined thickness and a second pattern with a second comb shape of a predetermined thickness. The electrode includes a first electrode formed on a portion of the first pattern and a second electrode formed on a portion of the second pattern. The dielectric elastic portion is interposed between the first electrode and the second electrode and contains a dielectric elastomer. Since the actuators can be laterally stacked, a multilayered actuator in which a large number (several to several thousands) of dielectric elastomer actuators stacked can be manufactured in the form of a very thin film (
