To provide a non-contact power supply system in which a leakage magnetic field is suppressed.SOLUTION: A non-contact power supply system comprises a power transmission device 1 and a power reception device 2. The power transmission device comprises: a power transmission coil 10, a magnetic material core 11, a first conductor plate 12, a housing 13 and a second conductor plate 14. The housing is a box shaped object of a rectangular parallelepiped, which surrounds the power transmission coil, the magnetic material core and the first conductor plate and in which a power reception device 2 side is opened. The housing comprises a bottom part 15 being a bottom face of the rectangular parallelepiped and side face parts 16 being four side faces of the rectangular parallelepiped. The bottom part 15 is constituted of ferrite. The side face parts are constituted of metal with larger conductivity than the bottom part.SELECTED DRAWING: Figure 1
