Abstract
A non-contact communication coil for a non-contact power feeding device comprises a power transmission coil, a power receiving coil, and a resonance coil, and the non-contact communication coil includes a first receiver and a second receiver connected in series with the first receiver. The non-contact communication coil generates induction voltages in mutually opposing directions in the first receiver and the second receiver when current passes through at least one of the power transmission coil and the power receiving coil.
