An actuator that swings a swing portion about a first axis and a second axis perpendicular or substantially perpendicular to each other, includes a fixed portion, two first stator cores, two second stator cores, two first coils, and two second coils. The first coil is in the same region as a tooth portion of the first stator core, and the second coil is in the same region as a tooth portion of the second stator core. As viewed in a central axis direction, each extending portion of each of the first stator cores includes end surfaces that face a magnet and oppose each other with the magnet interposed therebetween along the first axis, and each extending portion of each of the second stator cores includes end surfaces that face the magnet and oppose each other with the magnet interposed therebetween along the second axis.
