In the coil of the present invention, a primary wire partA and a secondary wire partB are wound around the surface of a core portionso as to be separated from each other by a fixed distance. At the same time, at least one portion the secondary wire partB in a prior turn sectionX and at least one portion of the primary wire partA in a subsequent turn sectionY are in close contact with each other, wherein the wire partsA andB are wound in different turns and are adjacent to each other on the same surface of the core portion. A method for manufacturing the wire-wound coil is also disclosed.
