A flat type vibration motor is provided to increase a driving torque by dually winding a coil to a rotor. A top cover(31) is coupled with a bottom cover(32). A shaft groove is formed in a center of the top cover. A shaft supporting part is formed in a center of the bottom cover. A supporting shaft(30) is vertically installed in a central part of an inner side of the top cover and the bottom cover. A stator(33) is arranged in an inner side of the bottom cover. A rotor(34) is rotatably installed in the supporting shaft, and corresponds to the stator. The rotor includes a plurality of coils(343,344). Each coil is dually wound in the rotor. A diameter of each coil is less than 0.035mm. A power supply unit(35) is arranged in the inner side of the bottom cover in order to supply a power to the rotor.
