Abstract
To minimize excessively high output or increases in magnetic-flux leakage by controlling power feeding on the power-feeding side if an unforeseen situation occurs. This power-feeding device () feeds power to an external power-receiving device () in a contactless manner. A power-feeding coil () uses electromagnetic power to feed electrical power to a power-receiving coil () in the power-receiving device (). While power is being fed from said power-feeding coil (), a power-feeding-side control unit () determines the amount of displacement of the power-feeding coil () and, on the basis of the determined displacement amount, controls the amount of electrical power being fed.
