PURPOSE: A wireless charging system is provided to achieve improved use convenience by eliminating the necessity of replacing a remote controller battery in case where the battery is discharged. CONSTITUTION: A wireless charging system comprises a charge region formed at the top of an electric product case such that the charge region accommodates a remote controller(200); a first coil(110) arranged at the inner surface of the electric product case, and which generates magnetic fields in accordance with the supplied AC voltage; a second coil(210) arranged in the remote controller, and which generates induction voltages from the magnetic field generated from the first coil at the state where the remote controller is accommodated in the charge region; a rectifying unit for smoothing the induction voltage generated from the second coil into a direct current; a constant voltage unit(220) for maintaining the direct current voltage smoothed through the rectifying unit at a predetermined level; and a battery(230) for charging the remote controller with the constant voltage output from the constant voltage unit.
