PROBLEM TO BE SOLVED: To provide an actuator which enables an operation to be performed in a pulling direction, while keeping power consumption low. SOLUTION: When a sheet body 1 is extended in a center-line direction thereof through application of a voltage to a conductive rubber layer of the sheet body 1 in a state in which an adjuster 12 on the reference end 1a side of the sheet body 1 of an actuator is fixed, a movable end 1b of the sheet body 1 is displaced in the direction of getting away from the reference end 1a. Thus, a wire 15 having a first sphere 16 fixed to the movable end 1b is displaced in a direction directed to the movable end 1b from the reference end 1a. Thereby, the wire 15 makes an operation object operated in a pulling direction. On the other hand, when the application of the voltage to the conductive rubber layer is released, the sheet body 1 is contracted in the center-line direction thereof. Consequently, the first sphere 16 (wire 15) fixed to the movable end 1b of the sheet body 1 is displaced in a direction directed to the reference end 1a from the movable end 1b.
