A foreign object detector includes a plurality of first coils and a plurality of second coils. The plurality of first coils are arranged along an upper surface of a power transmission coil. The plurality of second coils are provided to correspond to the plurality of first coils, with the second coils each being arranged to face a corresponding one of the first coils. An outer shape of each of the plurality of first coils and each of the plurality of second coils is smaller than an outer shape of the power transmission coil when the power transmission coil is viewed two-dimensionally from above the power transmission coil.
