PROBLEM TO BE SOLVED: To provide an electromagnetic induction coil used for a feeding system, capable of achieving impedance adjustment and maintenance with high efficiency without depending upon a variable capacitor.SOLUTION: A primary electromagnetic induction coil 5, supplying power supply to a primary resonance coil 6 of a pair of primary and secondary resonance coils 6, 7 for performing non-contact power feeding by magnetic field resonance, includes: a coil body 51, and a wedge W on which an end of the coil body 51 is installed to separate other portions. By adjusting a position of the wedge W, the number of windings of the coil body 51 is adjusted, thereby achieving impedance matching. |
