PROBLEM TO BE SOLVED: To provide a non-contact power transmission arrangement capable of preventing breakage or heating of a component on a power receiving device side when a load on the power receiving device side is in open state or in the case used with a low load. SOLUTION: The non-contact power transmission arrangement is characterised by comprising a power transmission device 5, a transformer 6, a power receiving device 7, and a load detection/power transmission controller 8. The power transmission device 5 generates an AC signal of the prescribed frequency to be transmitted. The transformer 6 efficiently transmits the power generated at the power transmission device 5 to the power receiving device 7 side. The load detection/power transmission controller 8 detects whether a load 73 to be connected to the power receiving device 7 is of no load or low load, and lowers the oscillation frequency of an oscillation circuit 51 of the power transmission device 5 down to a prescribed value in the case of no load or low load.
