Abstract
A wireless power feeding system capable of long distance and highly efficient space transmission of power is provided. A wireless power feeding system includes a power transmitter, a power receiver, and a power receiving body. The power transmitter generates electromagnetic waves. The power receiver is supplied with power by means of the electromagnetic waves received from the power transmitter using a magnetic field resonance phenomenon. The power receiving body is inserted into an electromagnetic field created by the power transmitter and the power receiver, and receives power by means of the electromagnetic field.
