Abstract
A wireless power feeding system is provided, which achieves a configuration enabling effective reception of electrical energy wirelessly transmitted from a wireless power feeding device, and which contributes to the improvement of the power reception efficiency. For the above purpose, the wireless power feeding system includes a power transmitting coil for wirelessly transmitting the electrical energy, a power supply connected to the power transmitting coil, a control unit for controlling the power supply, a power receiving coil portion for receiving the electrical energy transmitted from the power transmitting coil, a power receiving circuit for supplying a load member with the electrical energy received by a power receiving coil, and a magnetic member for collecting a magnetic flux generated by the power transmitting operation of the power transmitting coil to the power receiving coil.
