1. A wireless power supply device comprising:

  • a power transmission-side resonance circuit that resonates at a predetermined resonant frequency and inductively couples with a power reception-side resonance circuit to supply power wirelessly;

    a switching circuit that excites the power transmission-side resonance circuit at a predetermined frequency; and

    a control circuit that controls supplying power by controlling excitation of the switching circuit selectively at a plurality of frequencies among the resonant frequency and subharmonic frequencies for which the resonant frequency is divided by an odd number.
