<P>PROBLEM TO BE SOLVED: To increase the yield of a core provided to a primary coil in a non-contact power supply device. <P>SOLUTION: A through-hole 25 is formed in a core 20, whereby the amount of a raw material of a magnetic material required to manufacture each primary coil unit U1 can be reduced. Accordingly, the yield corresponding to the rate of the production number of coils 20 to the amount of the raw material of the coils 20 can be increased. <P>COPYRIGHT: (C)2013,JPO&INPIT |
