Abstract
A primary electromagnetic induction coil, which supplies power to a primary resonance coil in a pair of a primary and a secondary resonance coils that conduct non-contact power supply by magnetic field resonance, includes a coil main body and a wedge that mounts an end portion of the coil main body to separate the end portion from other portions. Impedance matching can be achieved by adjusting a position of the wedge and a number of turns of the coil main body.
