An electromagnetic actuator has a base plate including a plurality of electric wires queued in a queued direction at an interval. Each electric wire produces a magnetic field when supplied with current. A movable portion is mounted on the base plate and is movable relative to the base plate in the queued direction. The movable portion includes a pole surface facing toward the electric wires. The movable portion is moved in the queued direction when magnetic attraction or magnetic repulsion is generated between the pole surface and the magnetic field produced by each electric wire. The pole surface is magnetically attracted by at least one of the electric wires facing toward the pole surface when the movable portion is being moved in the queued direction.
