Abstract
There are provided with: a secondary winding 20 to which an electric power is supplied in a non-contact manner from a primary winding 10 by an alternating-current power source; a first circuit section 21 connected in parallel to the secondary winding 20; and a second circuit section 22 connected in series to a parallel circuit of the secondary winding 20 and the first circuit section 21. An impedance of the first circuit section 21 is larger than an impedance of the second circuit section.
