A power supply apparatus includes a power reception coil mounted to a moving object, a plurality of relay coils, and a power reception circuit connected with the power reception coil. The relay coils are configured to successively relay supply of electric power from a power transmission coil, which is arranged along a surface on which the moving object moves, to the power reception coil during movement of the moving object. Each of the relay coils includes a first coil and a second coil, which are configured to be magnetic-field-coupled respectively to the power transmission coil and the power reception coil, and a connection circuit that connects the first and second coils. The connection circuit includes at least one resonance capacitor involved in setting of a resonance frequency of at least one of the first and second coils. The at least one resonance capacitor has a parallel characteristic.
