PURPOSE: A brush of a flat type vibration motor is provided to improve the lifetime of a vibration motor by conforming the rotation direction of a rotor to the operation direction of the brush. CONSTITUTION: A flat type vibration motor includes a case, a winding coil, a rotor, and a brush. The development direction of the brush conforms to the rotation direction of the rotor. A bracket faces a case. A permanent magnet generates a magnetic flux and is formed on the inner surface of the bracket. A print circuit comprises a circuit which supplies external power. The brush transmits the external power to a commutator and supports the rotor.
