1. A wireless charging system for a vehicle which transmits electric power outputted from a feeding apparatus to a vehicle side in a non-contact manner to thereby charge a battery mounted on the vehicle, wherein the feeding apparatus includes:

  • an electric power output section which outputs AC power;

    a modulation section which superimposes a control signal on the AC power outputted from the electric power output section by using a predetermined modulation method;

    an electric power amplifying section which amplifies the AC power modulated by the modulation section; and

    a first communication terminal which transmits the AC power amplified by the electric power amplifying section, andwherein the vehicle includes;

    a second communication terminal which receives the AC power transmitted from the first communication terminal;

    a demodulation section which demodulates the AC power received by the second communication terminal to thereby extract the control signal; and

    a rectifying section which rectifies the AC power and supplies a DC power obtained by rectifying the AC power to the battery.
