  "textContent": "A wireless power transmission system according to the present invention includes: a pair of antennas 107 and 109, between which power is transmissible wirelessly by resonant magnetic coupling at a frequency f0, one of which is a series resonant circuit, and the other of which is a parallel resonant circuit; and a control section 100, which controls a transmission frequency according to the magnitude of the power being transmitted between the antennas 107 and 109. If the power transmitted between the antennas is greater than a reference value P1, the control section 100 sets the transmission frequency to be a value that falls within a first level range that is higher than the frequency f0. But if the power is smaller than the reference value P1, then the control section 100 sets the transmission frequency to be a value that falls within a second level range that is lower than the first level range.",
