  "textContent": "A power generator according to the present invention includes: a power generating section ( 101 ) for outputting DC energy; an oscillator ( 103 ) for converting the DC energy into RF energy having a frequency f0; a first antenna ( 107 ) for transmitting the RF energy; a second antenna, which receives, by coupling a resonant magnetic field, at least a part of the RF energy transmitted by the first antenna (107); and an output converting section ( 120 ) for converting the RF energy supplied from the second antenna ( 109 ) into AC energy having a lower frequency than the RF energy. If the oscillator ( 103 ) has a voltage step-up ratio Voc, the output converting section ( 120 ) has a voltage step-up ratio Vtr, the first inductor ( 107a ) of the first antenna ( 107 ) has an inductance L1, the second inductor ( 109a ) of the second antenna ( 109 ) has an inductance L2, and the first and second antennas ( 107, 109 ) have a coupling coefficient k, the power generator satisfies (L2/L1) § (k/(Voc×Vtr)) 2 .",
