摘要： A wide charging area and communication area are ensured in a non-contact power supply system with wireless communication. The present invention includes a resonance coil, a wireless communication antenna coil, a power supply coil, and a sensitivity adjustment circuit coupled to the power supply coil. When electric power is supplied in a contactless manner, the power supply coil and the resonance coil are coupled electromagnetically and electric power supply from the resonance coil is performed by using a magnetic resonance method. When wireless communication is performed, the magnetic fluxes of the wireless communication antenna coil are coupled with those of the resonance coil and sensitivity is enhanced by the sensitivity adjustment circuit.
