The present invention relates to a flat type vibration motor and a rotor structure, which can increase a vibration amount of the vibration motor by the rotor structure adapted to increase a volume of a weight formed on a substrate. The weight is formed with the stepped portion formed on the surface thereof, which is contacted with the substrate and the substrate is formed on an inserting hole or an inserting groove corresponding to the stepped portion, so that the stepped portion can be engaged with the inserting hole or the inserting groove. Alternatively, the weight is formed with a mounting groove and the substrate is formed with the inserting hole or the inserting groove and the fixing bar.
