Abstract
Power is fed from a feeding coil to a receiving coil using magnetic resonance. The feeding coil is wound in a first layer substrate 144 of a multilayer substrate 116 with a space provided between the coil conductor thereof and further wound in a second later substrate 146 with a space provided between the coil conductor thereof. The feeding coil is wound such that a coil conductor 106a in the first layer and a coil conductive wire 106b in the second layer do not overlap each other as viewed in the axial direction (z-axis direction).
