PURPOSE: A non-contact power supply system is provided to effectively reduce energy by supplying optimal power according to power consumption. CONSTITUTION: Three power supply units(31) are connected serially to a power supply line(12) through a transmitting/receiving coupler(32). A short circuit switch(38) short-circuits both ends of each power transmission coupler(32B). A circuit comprised of three power receiving couplers(32A) and a power supply line is set as a series-resonant circuit. The impedance of the circuit is set in a capacitive reactance in a fixed frequency. The constant current of the fixed frequency is outputted to the power supply line by controlling voltage outputted to the circuit.
