PROBLEM TO BE SOLVED: To provide maximal suppression of time-series reduction in the expansion/contraction ratio in an actuator where an electroconductive polymer immersed in an electrolyte is expanded or contracted by applying a voltage to the electroconductive polymer.SOLUTION: An actuator comprises an electroconductive polymer 10 and an electrolyte 20 where the electroconductive polymer 10 is immersed. The electrolyte 20 dissolves an antioxidant being soluble in an electrolyte 20 and preventing oxidation of the electroconductive polymer 10, and the electroconductive polymer 10 is expanded or contracted by voltage application to the electroconductive polymer 10 in the electrolyte 20. |
