The power transmission unit 3 is provided on the vehicle 30 side, and includes a power transmission coil (primary coil) 7, a switching circuit 8, and an oscillator 9. The power receiving unit 4 is provided on the electric device 50 side, and includes a power receiving coil (secondary coil) 10 and a rectifying / smoothing circuit 11 as a power receiving circuit.

When an AC current is supplied to the power transmission coil 7, for example, the power transmission coil 7 and the power reception coil 10 are electromagnetically inductively coupled to each other, and the power from the power transmission coil 7 is transmitted by electromagnetic induction or electromagnetic resonance. The power is received by the power receiving coil 10 in a non-contact manner. The power received by the power receiving coil 10 is converted from an alternating current to a direct current through the rectifying and smoothing circuit 11 and the like, and is used in the supplied part 51.

Thereby, when the power transmitting sheet 101 and the power receiving sheet 102 are positioned in the above-described positional relationship, the positioning unit 503 detects that each light receiving element 503a receives the light emitted by each light emitting element 503b (each By confirming that the electric signal of the light receiving element 503a has become larger than a predetermined threshold value), it is possible to detect that the power transmission sheet 101 and the power reception sheet 102 have been aligned in the above-described positional relationship. . As a result, in the wireless power supply system 1, the power transmitting coil 7 and the power receiving coil 10 face each other so that the transmission efficiency is relatively high, and the power receiving side communication coil 15 and the power transmitting side communication coil 13 face each other.
