A flat type vibration motor is provided to generate a large vibration force by separating a center of a weight and a center of a coil from a supporting shaft. A bracket(111) and a case(115) are coupled each other. One end of a supporting shaft(120) is supported in the bracket. The other end of the supporting shaft is supported in the case. A bearing(130) is rotatably installed in the supporting shaft. A rotor(140) has a rotor substrate(141), a coil(143), a weight(145), and a rotor yoke(149). The coil and the weight are coupled in the rotor substrate. The rotor yoke is coupled in the weight. The bearing is coupled in the rotor yoke. The rotor is integrally rotated with the bearing in order to generate vibration. A first magnet(161) and a second magnet(165) are installed in one surface of the case and the bracket.
