<p>PROBLEM TO BE SOLVED: To provide a non-contact power supply device which uses a steel tape formed by cutting out from a wound iron core as a magnetic circuit, reduces a leakage magnetic field to apply vertically to the surface of the steel tape, reduces an eddy current induced in the steel tape, and also can prevent a local overheating in the iron core of the magnetic tape from being generated. SOLUTION: A non-contact power supply device is constituted in such a structure that power is supplied from ground facilities to a carrier in a non- contact state by an electromagnetic induction via a primary side-conductor wire for flowing a high-frequency current and a secondary side-pickup coil. The iron core 13 of the pickup coil 12 is formed of stacked steel tapes 1a and 1b, and also non-magnetic metal plates 6 of an electrical permitivity higher than that of the steep tapes 1a and 1b are provided on the parts opposing to the primary side-conductor wires 11a and 11b of the steel tapes 1a and 1b.</p> |
