PURPOSE: To provide a noncontact power supply facility for feeding a mobile with power stably while preventing effect of magnetic field on the outside.

CONSTITUTION: Introduction lines 34 connected with a high frequency sine wave resonance inverter are laid along a guide rail B' while a coil 36 wound around a magnetic member, over the upper and lower surfaces thereof, is suspended, with the center thereof being matched with the center of the pair of vertical introduction lines 34, from a vehicle body being guided along the guide rail B'. The guide rail B' is made of a magnetic field shielding member while the introduction lines 34 and the coil 36 are configured to be surrounded by shield members in the moving direction of the vehicle body V. Upon conduction of the introduction lines 34 (with AC), flux generated from the introduction lines 34 passes through the coil 36 to induce electromotive force thus realizing noncontact power supply to the vehicle body V. Furthermore, magnetic shielding member surrounding the introduction lines 34 and the coil 36 shields magnetic field generated from the introduction lines to prevent effect of leakage flux on the outside and also blocks intrusion of foreign matter.
