PURPOSE: To provide a noncontact power supply facility for mobile which can feed the mobile with increased power at a predetermined position.

CONSTITUTION: An introduction line 21 connected with a high frequency sine wave resonance inverter is laid in a groove made along a guide path while a coil 27, formed by winding a litz wire around a ferrite 25, is suspended at a position above the introduction line 21 from a traveling body 22 which travels while being guided by the guide path and a ferrite 31 is disposed on the ground side oppositely to the ferrite 25 mounted on the traveling body 22 in the way of the introduction line 21 as a center. Upon conduction of the introduction path 21(with AC), electromotive force is induced in a coil 27 to realize noncontact power supply to the traveling body 22. Furthermore, since a magnetic path is established through the ground side ferrite 31 and the ferrite 25 mounted on the traveling body 22 at a predetermined position on the introduction line 21, power supply can be enhanced and the traveling body 22 can be fed with required load power stably.
