Abstract
An actuator has a plurality of pairs of a flexible electrode having flexibility, and a base electrode having an opposed face that is opposed to the flexible electrode and is covered with an insulating layer. The flexible electrode is configured to deform to get closer to the opposed face when a voltage is applied to the flexible electrode and the base electrode. Each of the pairs is located on the same axis, and adjacent ones of the pairs are connected to each other. The axis intersects with the opposed face of the base electrode of each of the pairs. The base electrode of each of the pairs is divided into a plurality of electrode portions insulated from each other, and the voltage is individually applied to the electrode portions.
