A1

The present invention addresses the problem of providing a power relay that, with a simple architecture, is capable of sending power from a magnetic-resonance power transmitter to an electromagnetic-induction electronic device. This power relay contains either a power transmitter, said power transmitter containing a primary-side coil connected to an AC power supply and a primary-side resonance coil that receives power from the primary-side coil via electromagnetic induction, or the following: a cover part attached to an electronic device containing a secondary-side coil; and a secondary-side resonance coil that is provided on the cover part and uses electromagnetic induction to send the secondary-side coil power received from the primary-side resonance coil via magnetic resonance therewith.
