Abstract
A wireless power-feeding apparatus that enables efficient wireless feeding to a power-receiving coil embedded at the center of a spherical power-receiving device. The apparatus includes: a holding member for holding the power-receiving device; a power-transmitting coil; a driver circuit for supplying the power-transmitting coil with high-frequency current to generate a magnetic flux for wireless power-feeding to the power-receiving coil; and a wireless data receiver for receiving data transmitted regularly from a wireless data transmitter, the power-transmitting coil being positioned relative to the holding member in such a manner that the axes of the power-receiving coil and the power-transmitting coil are parallel to each other when the power-receiving device is held by the holding member in such a manner that a mark provided on the surface of the power-receiving device faces a predetermined direction.
