PURPOSE:To facilitate the connection between coils by silver-soldering through an integrated connecting segment formed in a definite shape the first with the second coils. CONSTITUTION:A field coil is formed by connecting in series and laminating the first and the second coils 3 and 4 on which a coil conductor 1a is wound through a layer insulation. A connecting segment 10 is arranged so as to span between each coil conductor 1a of the first and the second coils 3 and 4. Which stepping sections A and B to the same thickness as that of a conductor for the multiple coil conductors 1a of the first and the second coils 3 and 4 at both ends, the connecting segment 10 is fitted to each coil conductor 1a of the first and the second coils 3 and 4 and silver-soldered. Thus, it becomes easy to perform silver-soldering of a connecting segment 10 with coil conductors 1a of the first and the second coils 3 and 4.
