PROBLEM TO BE SOLVED: To provide a non-contact power supply device capable of efficient power supply even if a distance between power feeding part and power reception part becomes larger.SOLUTION: A non-contact power supply device 45 includes a power feeding part 46 installed on side wall, floor, or ceiling, having a primary coil 49 connected to a high-frequency power supply 16, and a power reception part 48 installed on a vehicle or a transport carriage 47, disposed so as to oppose to the power feeding part with a gap, and having a secondary coil 58. At the back part of the helically-wound primary coil 49, a magnetic shield plate 57 is placed so as to cover the primary coil 49, and the secondary coil 58 and a secondary side resonant coil 59 are wound around a center magnetic pole 62 of an E-type core 61.SELECTED DRAWING: Figure 6 |
