PROBLEM TO BE SOLVED: To provide a non-contact power supply system capable of simultaneously supplying power to a plurality of power reception devices and capable of suppressing a manufacturing cost by supplying power to only a power transmission coil requiring power transmission.SOLUTION: A non-contact power supply system C supplies power from a power transmission device A to power reception devices B1 to B3 in a non-contact manner. The power transmission device A comprises: a high-frequency power supply device 4 for outputting a constant high-frequency voltage; power transmission units 11, 12, 13; switches 61 to 63 for performing switching of states of the respective power transmission units 11 to 13 between a state in which connection with the high-frequency power supply device 4 is established and a state in which separation from the high-frequency power supply device is established, respectively; and a control device 5 that, when the power reception devices B1 to B3 are disposed at a position at which power reception from any of the power transmission units 11 to 13 is possible, switches the switches 61 to 63 into a state in which the power transmission unit is connected. The power reception devices B1 to B3 comprise power reception units 21 to 23, respectively. A system for transmitting power from the power transmission units 11 to 13 to the power reception units 21 to 23 is a magnetic field resonance system.SELECTED DRAWING: Figure 1
