  • Patent number: 8723374
    Abstract: The disclosure provides a non-contact power receiving apparatus including a conductive pattern in a second region of a substrate not covered by a magnetic sheet. The conductive pattern includes first and second electrodes provided in a first plane parallel to a surface of the substrate and arranged in a length direction of the conductive pattern. A third electrode is formed on a second plane parallel with the first plane. A first via hole connects superposed portions of the first and third electrodes to each other, and a second via hole connects superposed portions of the second and third electrodes to each other. As a result, loops of eddy currents generated in the conductive pattern can be made to be small, whereby eddy current loss can be reduced.
