Abstract
An actuator includes a first magnet whose magnetic pole surface has an N pole and a second magnet whose magnetic pole surface has an S pole. When current flows from one end of a first wiring to the other end, the current circulates in one direction at least partially on the first magnet in a first area, while it circulates in a direction opposite to the one direction at least partially on the second magnet in the first area. When current flows from one end of a second wiring to the other end, the current circulates in the direction opposite to the one direction at least partially on another first magnet in the second area, while it circulates in the one direction at least partially on another second magnet in the second area.
