A brush of a flat type vibration motor is provided to extend a life span of the motor by enabling an arm of the brush to press a flat type commutator with uniform contact pressure. In a brush of a flat type vibration motor, a plurality of arms(21,22,23) is contacted to a flat type commutator on the substantially same plane. A supporting unit supplies current to the arms(21,22,23) by being electrically connected to a current source, and fixes and supports the brush. The plurality of arms(21,22,23) is applied by the substantially same contact pressure when being contacted to the flat type commutator.
