Abstract: A linear actuator includes: a coil that is movably provided; a coil yoke that is provided to move integrally with the coil; a first side yoke portion that extends outside of the coil; a second side yoke portion that is surrounded by the coil, extends, and is opposed to the first side yoke portion; and a magnet that forms a magnetic field between the first side yoke portion and the second side yoke portion. The coil yoke extends along an axis of the coil. The first side yoke portion and the second side yoke portion have a first hold portion and a second hold portion, the support portion supporting the coil yoke in a stop position and having magnetic polarities.
