PROBLEM TO BE SOLVED: To provide a non-contact power supply system that is simple and high in reliability, and can control a voltage fed to a load. SOLUTION: The non-contact power supply system comprises a power supply which generates a supply-side current and a supply-side voltage for feeding power to the load; a primary coil which inputs power from the power supply; a secondary coil which is electrically connected to the primary coil, whose position to the primary coil is movable, and which feeds power to the load; a first resonance capacitor connected to the primary coil; and a secondary resonance capacitor connected to the secondary coil. The power supply comprises a current detector which detects the supply-side current; an operation part which operates the value of the supply-side current for setting a load-side voltage fed to the load as a prescribed target value, on the basis of the detection result of the current detector; and a voltage control unit which controls the supply-side voltage according to the operation result of the operation part.
