The present invention relates to a flat vibration motor. According to an embodiment of the present invention, the flat vibration motor comprises: a weight including a housing where an inner space is formed, having a magnet provided in the inner space, and rotating on an axis in the inner space; and a multi-layered circuit board (MLB) arranged to face the magnet, and formed to stack a coil pattern coil for generating an electromagnetic force between magnets. Accordingly, by using the MLB instead of using a coil, the use of the inner space can be maximize without having a soldering space between coils, thereby increasing convenience of manufacturing since handling the MLB is easier than handling the coil. |
