<P>PROBLEM TO BE SOLVED: To improve power transmission efficiency of a contactless power supply device. <P>SOLUTION: Core pots 20a-20e have outer peripheral parts 24 covering outer peripheries of primary coils L1a-L1e. Consequently, distances between the outer peripheral parts 24 as magnetic bodies and cores corresponding to secondary coils can be made short without reference to winding diameters of the primary coils L1a-L1e (i.e. axial sizes of the primary coils). The degree of coupling between the primary coils and secondary coils, i.e. the power transmission efficiency can be improved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
