PROBLEM TO BE SOLVED: To provide a contactless power reception device, a contactless power feeding system, and an electric vehicle, which are capable of handling both normal charging and quick charging.SOLUTION: A contactless power reception device 10 comprises a power receiving coil which is arranged to face a power transmitting coil 31 of a power transmitting device 30. The contactless power reception device 10 comprises a capacitor which is connected in parallel with the power receiving coil 11 and which can be turned on/off or has a variable capacity. In a state where the capacitor is off or the capacity of the capacitor has been adjusted to be small, quick charging is performed with the quick charging power transmitting coil 31 disposed closely to the power receiving coil 11. In a state where the capacitor is on or the capacity of the capacitor has been adjusted to be large, normal charging is performed with a normal charging power transmitting coil disposed to face the power receiving coil 11 via a prescribed gap therebetween.SELECTED DRAWING: Figure 1
