Abstract:
A coil module includes a magnetic substance plate, a first coil, and a second coil. The magnetic substance plate includes a first area having a first magnetic permeability and a second area having a second magnetic permeability. The first coil is disposed on a surface of the magnetic substance plate. The second coil is disposed on the surface of the magnetic substance plate and partially overlapping the first coil. A portion of the first coil, not overlapping the second coil, is disposed on a surface of the first area, and a portion of the second coil, not overlapping the first coil, is disposed on a surface of the second area.
