A power transmitting antenna includes a first resonant circuit including a power transmitting coil, a power receiving antenna includes a second resonant circuit including a power receiving coil. When the power transmitting antenna and the power receiving antenna are electromagnetically coupled to each other, the power transmitting antenna and the power receiving antenna have an odd-mode resonance frequency corresponding to an odd-mode resonant condition, and an even-mode resonance frequency corresponding to an even-mode resonant condition, and the even-mode resonance frequency is higher than the odd-mode resonance frequency. A wireless power transmitting apparatus is provided with a power transmitting circuit configured to generate high-frequency power at a variable frequency, and supply the high-frequency power to the power transmitting antenna. A control circuit sets the frequency of the high-frequency power generated by the power transmitting circuit to one of the odd-mode resonance frequency and the even-mode resonance frequency.
