A cylindrical magnet of an oscillating actuator includes a plurality of divided magnet portions which are magnetized in the radial direction. Since adjacent magnet portions have different poles in the direction of an oscillation axis, magnetic poles do not repel each other when adhering the magnet portions and it is thus easy to adhere the magnet portions to each other. In addition to this construction of the magnet, a coil includes a plurality of divided coil portions corresponding to the magnet portions in the direction of the oscillation axis, and adjacent coil portions are wound in opposite directions to each other.
