    Abstract: The present invention is a power feeding system that includes a power transmission device and a power receiving device. The power transmission device includes a primary side coil. The power receiving device includes a secondary side coil. The power receiving device side performs an adjustment such that a value of a current supplied to a load becomes a predetermined value. Thus, the present invention solves a problem of a conventional power feeding system that, for example, an increase in a current value supplied to a load possibly damages the load. The power receiving device receives electric power output from the power transmission device that includes a primary side coil. The power receiving device is configured to supply electric power according to the electric power to the load. The power receiving device includes a secondary side coil and an adjusting device. In the secondary side coil, a second current is generated according to a first current which is supplied to the primary side coil.
