PROBLEM TO BE SOLVED: To provide a contactless power supply system which devises a structure and arrangement of a tertiary coil connected to a resonance capacitor and a secondary coil generating power supplied to a load, separates a distance between a power supply part and a power receiving unit and obtains a larger current as a secondary current. SOLUTION: The contactless power supply system 10 is provided with the power supply part 11 which is arranged in a fixed state and has the primary coil 14 connected to a high-frequency power supply 15, and the power receiving unit 13 which is loaded on a mobile vehicle 12, is oppositely disposed in the power supply part 11 with a gap, has the secondary coil 17 and the tertiary coil 18, which are magnetically coupled to the primary coil 14, and generates power supplied to the load 37 in the secondary coil 17 and in which the resonance capacitor 35 is connected to the tertiary coil 18. The secondary coil 17 and the tertiary coil 18 are separately installed. The tertiary coil 18 is arranged on a front side nearer to the primary coil 14 rather than the secondary coil 17.
