Abstract
A portable electronic device includes a housing, a secondary battery disposed inside a tip portion of the housing, and a power receiving coil unit disposed around the secondary battery. The power receiving coil unit has a first coil in which a conductive wire is helically wound around a first magnetic body and a second coil in which a conductive wire is wound helically around a second magnetic body. The first magnetic body and the second magnetic body are disposed between an outer side surface of the secondary battery and an inner side surface of the housing. The first coil and the second coil are located at mutually different positions in a direction around an axis of the secondary battery and are interconnected such that opposed magnetic flux is generated in respective winding axes when current flows the first and second coils.
