PURPOSE: A manipulator using a permanent magnet and a driving device including the same are provided to prevent power waste by continuously maintaining the operation completion state of a mover through the force of an open spring and the magnetic force of the permanent magnet. CONSTITUTION: A stator(1100) comprises a fixing iron core(1120), an input side coil(1140) and an open side coil(1150). The fixing iron core is made of magnetic materials. The input side coil and the open side coil are wound around the fixing iron core. A mover(1200) moves to the input and open positions and includes the permanent magnet. An open spring(2000) is arranged between the stator and the mover to support the mover.
