Abstract
A reception pad for a wireless power transfer (WPT) system includes: a plate-shaped ferrite; an insulating layer disposed on one side of the ferrite; a first coil layer disposed on the insulating layer; an interlayer insulating layer disposed on the first coil layer; and a second coil layer disposed on the interlayer insulating layer. The insulating layer at least partially surrounds the first coil layer and the second coil layer, the first coil layer and the second coil layer at least partially overlap each other and are arranged in a rectangular ring form on the one side of the ferrite, and a ratio of a width which is larger between a first width of the first coil layer and a second width of the second coil layer to a first length of the ferrite in a width direction corresponding to the first width or the second width is 0.14 to 0.15.
