A contactless power feeding system includes a power transmitting device and a power receiving device. The power transmitting device includes a first AC power source configured to generate an AC power with a first frequency, a second AC power source configured to generate an AC power with a second frequency which is different from the first frequency, a first electromagnetic induction coil, and a first resonant coil. The power receiving device includes a second resonant coil, a second electromagnetic induction coil, and a power storage unit. Power is wirelessly supplied to the power storage unit at the second frequency by a magnetic resonance phenomenon which occurs between the first resonant coil and the second resonant coil.
