A wireless power feeder feeds power from a feeding coil Lto a receiving coil Lby wireless using a magnetic field coupling between the feeding coil Land the receiving coil L. The feeding coil Lis formed so as to be rotated. A power transmission control circuit supplies AC power to the feeding coil Lto make the feeding coil Lfeed the AC power to the receiving coil L. The power transmission control circuit rotates the feeding coil Lto change the opposing area between the feeding coil Land the receiving coil Las viewed in the axis direction of the feeding coil Lto thereby adjust the AC power to be supplied from the feeding coil Lto the receiving coil L
