Title:
COIL, COIL PRODUCING METHOD, AND COIL MODULE
Document Type and Number:
WIPO Patent Application WO/2011/001812
Kind Code:
A1
Abstract:
Provided are a coil, a coil producing method, and a coil module, wherein a magnetic shield function can be enhanced on the entire surface of a spiral conductor other than the surface to be electromagnetically coupled, losses in the electromagnetic coupling can be reduced, and the production cost can be reduced.
A coil (10) is provided with a spiral conductor (2) formed in the shape of a plate, and a plastic structure (3) in the shape of a plate which contains a magnetic material. The coil (10) contains the spiral conductor (2) biased toward one surface of the plastic structure (3). Further, a part of the spiral conductor (2) is exposed toward the outside on one surface of the plastic structure (3). Further, the coil module is comprised of the coil (10) and a circuit substrate electrically connected to the coil (10), to which a predetermined circuit for processing electric signals passing through the coil (10) is mounted.
