1. A non-contact charge and communication system comprising:

  • non-contact charge apparatus including a power transmitting device that transmits power for a charge by magnetic field coupling and a first communication unit that carries out non-contact communication by electric field coupling; and

    power receiving apparatus including a power receiving device that receives power transmitted from the non-contact charge apparatus based on a magnetic field resonance relationship and a second communication unit capable of non-contact communication with the first communication unit by electric field coupling, and charge a battery by received power,wherein,the non-contact charge apparatus including a first control unit that transmits charge-exchange delivered data to the power receiving apparatus existing in a magnetic field of the power transmitting device by the first communication unit, and transmits power permitting a charge of the battery by the power transmitting device if the first communication unit receives a reception-completion notification of the charge-exchange delivered data by the second communication unit of the power receiving apparatus, andthe power receiving apparatus includes (a) a storage unit, and (b) a second control unit that stores the charge-exchange delivered data that has been received in the storage unit and transmits the reception-completion notification to the first communication unit if the second communication unit receives the charge-exchange delivered data by the first communication unit.
