Abstract: A wireless charging apparatus is disclosed. The wireless charging apparatus includes a plurality of coil arrays disposed so as to partially overlap each other, and a shielding member disposed at one side of each of the coil arrays to block a leaked magnetic field. The coil arrays include a first coil array including a plurality of transmission coils disposed adjacent to each other, a second coil array including a smaller number of transmission coils than the first coil array and disposed under the first coil array, and a third coil array including the same number of transmission coils as the second coil array and disposed on the first coil array. As a result, it is possible to simultaneously charge a plurality of devices requiring different amounts of power.
