Abstract
A coil unit performs at least one of transmission and reception of electric power using electromagnetic resonance between the coil unit and a primary resonance coil disposed to face the coil unit. The coil unit includes a secondary resonance coil (110A, H0B) that includes a plurality of coils, and that electromagnetically resonates with the primary resonance coil. A first coil among the plurality of coils is disposed in a manner such that a magnetic field generated by the first coil has a phase opposite to a phase of a magnetic field generated by at least one coil other than the first coil among the plurality of coils, with respect to a plane that faces the primary resonance coil.
