A method capable of efficiently adjusting both the resonance frequency and impedance of a resonant system in contactless power transmission by a resonance method is provided. A variable capacitor (220) adjusts a resonance frequency of a secondary self-resonant coil (210). An impedance matching box (250) adjusts an input impedance of a resonant system. An ECU (290) first adjusts the resonance frequency of the secondary self-resonant coil (210) by controlling the variable capacitor (220), and after the adjustment of the resonance frequency, adjusts the input impedance of the resonant system by controlling the impedance matching box (250). During the adjustment of the resonance frequency by the variable capacitor (220), the ECU (290) sets an impedance of the impedance matching box (250) to a predetermined fixed value.
