Abstract (en)
A hollow conductor (22) which is rectangular in section is wound in a spiral to form a single pancake coil (20). A prepreg tape (40) is sandwiched between the already-wound portion (28) and the to-be-wound portion (30) of the conductor (22) when the conductor is wound. The single pancake coil (20) which has been wound with the prepreg tape (40) sandwiched is press-fixed by a metal frame, for example, and then heated, whereby resin impregnated in the prepreg tape is made liquid to fill between the overlapped faces of the conductor (22) so as to make the conductor (22) adhered at its overlapped faces and to electrically insulate one of the overlapped faces from the other. In the case of coaxially putting the single pancake coils (20) one upon the other to form a double pancake coil, a prepreg sheet (42) is sandwiched between the single pancake coils (20) and then heated to fix the single pancake coils with each other and to insulate the single pancake coils from each other.
