PURPOSE: A flat type vibration motor is provided to tenuously form the thickness of a motor as the height of a cradle groove by injecting and settling a coil in the cradle groove formed in a rotor substrate and a substrate. CONSTITUTION: A central axis(120) supports the inside of a housing(110). In the central axis, a bearing(130) is installed to be rotatable. A coil(163) and a weight(165) are respectively installed in a rotor substrate(161). A supporting member unites the rotor substrate, the coil, and the weight in a body. A rotor is installed in the supporting shaft to be rotatable and generates vibration. A stator is installed in the inside of the housing and rotates the rotor by operating with the rotor.
