PURPOSE: Oval-shaped monodisperse hybrid particles are provided to enable the arrangement and driving according to the control of a magnetic force by reacting with the orientation of the magnetic force. CONSTITUTION: A method for preparing oval-shaped monodisperse hybrid particles in which inorganic particles having magnetism are introduced comprises the steps of: injecting a radically polymerizable monomer, a dispersing stabilizer, a cross-linking agent and an initiator into a solvent, and preparing oval-shaped monodisperse hybrid particles in which the injection weight of the cross-linking agent is 0.01~5 weight% based on 100 weight% of the total weight of the radically polymerizable monomer, the dispersing stabilizer, the cross-linking agent, the initiator and the solvent; introducing inorganic particles having magnetism to the manufactured polymer particles; and washing and drying the oval-shaped monodisperse hybrid particles to which the inorganic particles having magnetism is introduced.
