To provide a movable feed type non-contact power supply apparatus in which, while firstly maintaining radiation electromagnetic field suppression effects, pulsation of received power can be suppressed secondly.
A non-contact power supply apparatus 1 is configured as a movable power feed type in which, on the basis of mutual induction of electromagnetic induction, power is supplied from a power transmitting coil 3 of a power supply side circuit 2 to a power receiving coil 7 of a power reception side circuit 5 and in the case of power supply, the power receiving coil 7 moves while keeping an air gap with respect to the fixed power transmitting coil 3. The power transmitting coil 3 is structured flat and formed in a long loop shape in a moving direction B of the power receiving coil 7 and crosses the moving direction in the middle, and a plurality of units 4 are formed by crossing. The power receiving coil 7 is loop-shaped and structured flat, and a plurality of receiving coils are disposed at an interval (d). Zero received power in the case where any power receiving coil 7 is positioned in counter to a crossing position of the power transmitting coil 3, is covered by normal received power of the other power receiving coils 7.
