Zusammenfassung:	[Problem to be Solved] To efficiently perform non-contact power supply that is carried out using a relay apparatus. [Solution] A non-contact power supply system 1 compares transmission efficiency between a case of a first route mode of indirectly supplying power from a power supply apparatus 10 to a power receiving apparatus 20 through a relay apparatus 30 and a case of a second route mode of directly supplying power without interposing the relay apparatus 30, and selects a route of higher transmission efficiency to supply the power. In the case of the first route mode, a power supply circuit 14 of the power supply apparatus 10 and a power receiving circuit 31 of the relay apparatus 30 are made to resonate, and a power transmission circuit 32 of the relay apparatus 30 and a power receiving circuit 21 of the power receiving apparatus 20 are made to resonate, but the power supply circuit 14 of the power supply apparatus 10 and the power receiving circuit 21 of the power receiving apparatus 20 are not allowed to resonate. In the case of the second route mode, the power supply circuit 14 of the power supply apparatus 10 and the power receiving circuit 21 of the power receiving apparatus 20 are made to resonate, but the power supply circuit 14 of the power supply apparatus 10 and the power receiving circuit 31 of the relay apparatus 30 are not allowed to resonate.
