ACTUATOR MANUFACTURING METHOD
First Claim
1. A method for manufacturing an actuator formed by rolling a sheet in which dielectric elastomer layers and conductive rubber layers are stacked along a direction of thickness, wherein, when voltage is applied to the conductive rubber layers in the sheet, the actuator expands the rolled sheet along an axial direction of the rolled sheet, and when the application of the voltage is stopped, the actuator contracts the rolled sheet along the axial direction, the method comprising;
- alternately stacking a plurality of dielectric elastomer layers and a plurality of conductive rubber layers along a direction of thickness, thereby forming a single sheet; and
wrapping the sheet formed in the step of alternately stacking about a core, thereby obtaining a rolled sheet.

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.
