Abstract: The electricity supply device (100) supplies electricity using electromagnetic force and opposes an external electricity reception coil (153a). An electricity supply coil (102a) has a hollow section (102b), and has a spiral shape. A reader (103) has an antenna disposed in the projected space resulting from projecting the hollow section (102b) in the central axial direction of the electricity supply coil (102a) and at a position more separated from the electricity reception coil (153a) than the opposing surface that opposes the electricity reception coil (153a) and is of the electricity supply coil (102a), and ID data transmitted by an RF tag (154) installed proximally to the electricity reception coil (153a) is received and detected by the antenna. An electricity-supply-side control unit (104) determines the presence/absence of an electricity reception coil (153a) on the basis of the ID data detected by the reader (103).

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 (100) feeds power to an external power-receiving device (150) in a contactless manner. A power-feeding coil (103) uses electromagnetic power to feed electrical power to a power-receiving coil (154) in the power-receiving device (150). While power is being fed from said power-feeding coil (103), a power-feeding-side control unit (107) determines the amount of displacement of the power-feeding coil (103) and, on the basis of the determined displacement amount, controls the amount of electrical power being fed.
