PLANE COIL

摘要

A plane coil which reduces an increase of an effective resistance in a high-frequency area and is made thinner is provided. A plane coil 10 equipped with plural conductive wires 11 which are parallel to each other, wherein the conductive wires are arranged in a plane and spirally wounded, and coil ends 13a and 13b of the respective conductive wires 11 are electrically connected to each other at coil lead-out portions 12a and 12b and thus are connected in parallel. The conductive wires 11 are arranged in plane, so that a coil thickness does not increase, and the coil 11 is made thinner. Moreover, the plural conductive wires 11 are connected in parallel, an increase of an effective resistance due to an influence of a skin effect in a high-frequency area is reduced.
