Abstract:
A coil unit includes a second resonance coil that has a plurality of unit coils and performs at least one of transmission and reception of electric power to and from a first resonance coil spaced apart from the second resonance coil via electromagnetic resonance with the first resonance coil. The directions of magnetic fields formed by the unit coils are the same.
