Abstract
A wireless power transmission apparatus includes a shielding plate, a transmission coil on the shielding plate, and a shielding member disposed on the shielding plate and configured to surround the transmission coil. The shielding plate may shield a magnetic field formed to a lower side of the transmission coil. The shield member can offset the magnetic field formed on the side of the transmission coil. Thus, the embodiment can minimize EMI or EMF caused by the magnetic field formed on the lower side and the side of the transmission coil.
