Abstract
Provided is an actuator that increases thrust while reducing mass of a magnetic field generating member including a magnet and a yoke, compared to conventional actuators. An actuator in the present disclosure includes a magnetic field generating member having a multipole-magnetized magnet and a yoke disposed on a first surface of the multipole-magnetized magnet, and a coil member provided in a position confronting a second surface of the multipole-magnetized magnet. The yoke is formed of a member narrower in width than the first surface of the multipole-magnetized magnet.
