<P>PROBLEM TO BE SOLVED: To provide a noncontact power supply device for supplying power to a mobile body capable of facilitating the manufacturing of a power supply section and power receiving section at low cost, and capable of transmitting high power. <P>SOLUTION: The noncontact power supply device of the mobile body comprising the power supply section 1 provided on a surface where the mobile body moves, and the power receiving section 2 provided in a position facing to the power supply section 1 of the mobile body lower part. The power supply section 1 and the power receiving section 2 comprise windings 4 formed in an oblong shape, and a plate-like core 3 of a magnetic body with a recessed part 8 formed on its surface for housing the winding so that the winding of the oblong direction is along a moving direction (a) of the mobile body. The plate-like core 3 is formed by arranging a plurality of plate-like blocks 5 having a rectangular surface in the moving direction (a) or a direction orthogonal to the moving direction, or superimposing vertically with a long side 5a of the rectangular facing to the moving direction (a). The recessed part 8 of the plate-like core 3 is formed by arranging a thick part 7 formed by superimposing the plate-like blocks 5 on a plate-like core surface on an inner side and an outer side of the oblong part of the winding 4. <P>COPYRIGHT: (C)2008,JPO&INPIT |
