PROBLEM TO BE SOLVED: To provide a non-contact power supply pad external dimensions of which can be reduced while facilitating the production.SOLUTION: A non-contact power supply pad includes a planar first ferrite 14 having magnetic pole regions 12, 13 set at both ends, respectively, and coils 16, 17 wound spirally around the magnetic pole regions 12, 13 of the first ferrite 14 from the outside of the end thereof across the upper surface of the body of first ferrite 14. The coils 16, 17 are wound planarly in one stage on the upper surface of the body of first ferrite 14, respectively, and wound in two stages vertically on the outside of the end of first ferrite 14. A voltage is applied to the two coils 16, 17, so that a magnetic flux path is formed to pass above the first ferrite 14 from one of the magnetic pole regions 12, 13 to the other. |
