Zusammenfassung:	A contactless power transmission system is provided for supplying power contactlessly from a power transmission apparatus to a power reception apparatus. The power transmission apparatus includes a high-frequency power source device for outputting a constant high-frequency current, and power transmission units having serial resonance circuits. The power reception apparatus includes power reception units having parallel resonance circuits. A power transmission coil of the power transmission unit and a power reception coil of the power reception unit are magnetically coupled. The power transmission units are connected in series, while the power reception units are connected in parallel. Power is transmitted from the power transmission unit to the power reception unit by magnetic field resonance.
