Abstract: With a non-contact power supply system, a non-contact power supply device, and power supply target device of the present invention, power is supplied from a power supply coil of the non-contact power supply device to a power receiving coil of the power supply target device by non-contact power supply utilizing magnetic interaction. During the non-contact power supply, first, a power supply coil exhibiting a first interaction stronger than a predetermined reference interaction is selected as a candidate excitation coil, and a high-frequency voltage is supplied to the power supply coil of the candidate excitation coil. Second, a power supply coil exhibiting a second interaction weaker than the reference interaction and power supply coils adjacent to this power supply coil are selected as candidate excitation coils, and the high-frequency voltage is supplied to the power supply coils of these candidate excitation coils.
