Abstract

The subject of the present invention is to provide a flat air core coil wherein the electric insulation is improved, and deformation due to secondary heating is prevented. To achieve the subject, the flat air core coil comprises a first coil (8) composed of a wound rectangular copper wire and a second coil (9) composed of a rectangular copper wire wound in a direction opposite to that of the first coil (8). The first coil (8) and the second coil (9) are electrically connected with each other, and an insulating film (18) is interposed between the first coil and the second coil.
