Summary:PURPOSE:To eliminate a layer shortcircuit due to the damage of an insulating film of a coil strand by arranging a ring-shaped solder printed board on the cylindrical end faces of inner and outer coils, filling it in a furnace and soldering it. CONSTITUTION:A plurality of conductive units 8 which can be electrically connected to the ends of the coil strands of inner and outer cylindrical coils disposed oppositely on the surface of a ring-shaped solder printed board 7. The board 7 is pressed and disposed on both upper and lower end faces of inner and outer cylinders in such a manner that the pattern of the units 8 coincides with the ends of the corresponding strands, inserted into a furnace, and soldered, thereby bonding the ends of the strands of the inner and outer cylindrical coils.
