CONTACTLESS ELECTRICITY SUPPLY SYSTEM

In this non-contact power supply system that, by means of at least a magnetic coupling, supplies power in a non-contact manner between a power transmission coil (11) provided to a power supply device (1) and a power reception coil (21) provided to a vehicle (2): the vehicle (2) comprises a vehicle side communication means that permits power transmission from the power transmission coil (11) to the power reception coil (21) with respect to one power supply device (1) among a plurality of power supply devices (1) and transmits a permission signal including identification information of the one power supply device (1), a power detection means that detects the power that is received by the power reception coil (21), and a determination means that determines whether or not a paired communication has been established between the vehicle (2) and the power supply device (1); the power supply device (1) comprises a power supply device side communication means that receives the permission signal, and a control means that outputs power from the power transmission coil (11) to the power reception coil (21); the control means outputs power from the power transmission coil (11) to the power reception coil (21) when the identification information of a power supply device (1) and the identification information included in a permission signal that is received by a power supply device side communication means match; and the determination means determines that a paired communication has been established between one power supply device (1) and a vehicle (2) when the power is detected by a power detection means.
