PROBLEM TO BE SOLVED: To ensure a charging area and a communication area wide in a non-contact power feeding system with radio communication.SOLUTION: The non-contact charger includes: a resonance coil; a radio communication antenna coil; power feeding coil; and a sensitivity adjustment circuit connected with the power feeding coil. In feeding electric power in a non-contact mode, the power feeding coil and the resonance coil are electromagnetically coupled to each other, power feeding is performed from the resonance coil, using a magnetic resonance system. In radio communication, the radio communication antenna coil and the resonance coil are coupled to each other for high sensitivity through the sensitivity adjustment circuit.SELECTED DRAWING: Figure 1A |
