Abstract: An axial-gap coreless rotary electric machine includes rotors, stators, and a case. Armature coils of the stators include a first coil segment and a second coil segment facing the first coil segment. The case includes a first case segment and a second case segment facing the first case segment.

Abstract: A method of manufacturing a bar antenna having a magnetic core incorporated therein includes removing a covering material from each end portion of parallel covered cords, the parallel covered cords being separated from each other by a length required for winding on the magnetic core, the portions wherefrom the covering material is removed being connected together. A winding start position is set beforehand so that an end portion of the magnetic core can be matched in position with the winding end of a coil. One cord, a connecting portion and the other cord are wound in sequence consecutively from the start position to the end portion of the magnetic core, starting from the base of the separated portions of the cords, so as to form the coil, and thereafter the coil thus formed is transferred to a prescribed position, while the portions of the parallel covered cords not separated from each other are used as an extension cord as they are.
