Summary:To provide a gel actuator in which a large displacement can be obtained from a low application voltage.SOLUTION: A gel actuator 1 includes: a gel layer 11 in which a plurality of projections 10 each containing a dielectric polymer material are provided; a positive electrode 12 that is disposed in contact with the tops of the projections 10; and a negative electrode 13 that is positioned opposed to the positive electrode 12 with the projections 10 interposed therebetween in the height direction. Each projection 10 has a conical shape, and the maximum width of the bottom surface of each projection 10 is equal to or less than 1 mm.SELECTED DRAWING: Figure 1 【課題】低い印加電圧で大きな変位量を得ることができるゲルアクチュエータを提供する。【解決手段】誘電性高分子材料を含む突部１０を複数備えるゲル層１１と、突部１０の頂部に接して配される正極１２と、正極１２に対し、突部１０を高さ方向に挟む位置に配される負極１３と、を備えるゲルアクチュエータ１において、突部１０が錐型をしており、突部１０の底面の最大幅が１ｍｍ以下となるゲルアクチュエータ１。【選択図】図１
