Abstract

An actuator manufacturing method includes alternately stacking a plurality of dielectric elastomer layers and a plurality of conductive rubber layers along the direction of thickness to form a sheet, and wrapping the sheet formed about a core to form a rolled sheet. When the sheet formed in the step of alternately stacking is wrapped about the core, the sheet is formed by the dielectric elastomer layers and the conductive rubber layers. Therefore, even if the dielectric elastomer layers in the sheet are made to be thin, the thickness of the entire sheet is prevented from being excessively thin.
