    • PROBLEM TO BE SOLVED: To efficiently supply power from an AC power supply to a load without changing a frequency of an AC output voltage of the AC power supply, even if at least either the distance between two resonant coils or the load changes.
      SOLUTION: The non-contact power transmission apparatus 10 includes: an AC power supply 11; a primary coil 12 connected to the AC power supply 11; a primary side resonant coil 13; a secondary side resonant coil 14; a secondary coil 15 having a load 16 connected thereto; and an impedance variable circuit 17 provided between the secondary coil 15 and the load 16. A resonant system 20 is configured by the primary coil 12, the primary side resonant coil 13, the secondary side resonant coil 14, the secondary coil 15, the load 16 and the impedance variable circuit 17. The AC power supply 11 outputs an AC voltage at the frequency same as the resonant frequency of the resonant system 20, and the impedance variable circuit 17 adjusts the impedance so as to suppress a change in an input impedance of the resonant system 20.
