PROBLEM TO BE SOLVED: To effectively suppress radiation noises in a contactless power supply device which transmits and receives power contactlessly.SOLUTION: A power transmission coil 12 which contactlessly transmits and receives power to/from a receiving coil with magnetic coupling has a spirally wound structure in a prescribed plane. The power transmission coil 12 has a first capacitor 13i connected in series with an inner terminal of the coil 12, and a second capacitor 13o connected in series with an outer terminal of the coil 12. In this case, a ratio Ci/Co of a capacitance Ci of the first capacitor 13i and a capacitance Co of the second capacitor 13o is set in a prescribed relation. |
