A tubular magnet of a vibration actuator includes a plurality of magnet units magnetized in the radial direction and divided in the vibration axis direction. Since the adjacent magnet units have different poles in the vibration axis direction, repulsion between the poles does not occur during junction, and the magnet units are easy to be joined together. Since the magnet has such a construction, a coil includes a plurality of coil units divided in the vibration axis direction corresponding to each of the magnet units, and the winding directions of wires of the adjacent coil units are opposite. |
