Title:

PLANE COIL

Document Type and Number:

WIPO Patent Application WO/2010/001749

Kind Code:

A1

Abstract:

Disclosed is a plane coil which is made thin while an increase in effective resistance in the high frequency region is minimized. A plane coil (10) is configured such that a plurality of electrically conductive wires (11) arranged in parallel with each other are wound spirally while being arranged planarly, and are connected in parallel because the ends (13a) of the respective electrically conductive wires (11) are connected electrically with each other at a coil lead-out portion (12a) and the ends (13b) thereof are also connected with each other at a coil lead-out portion (12b). Since the electrically conductive wires (11) of the plane coil (10) are arranged substantially planarly, coil thickness does not increase and the plane coil (10) is made thin. Furthermore, an increase in effective resistance due to skin effect is minimized in the high frequency region because the plurality of electrically conductive wires (11) are connected in parallel.
