PURPOSE: To facilitate the winding work and the joint work of a plurality of coils and facilitate performing those works within the electrically required minimum dimension between the respective coil sections by a method wherein the respective tip parts of the winding start leads of the adjacent coils are mutually jointed and an insulation is applied to the joint part to isolate the joint part from the environment electrically and then the joint part is positioned at the winding position of both the winding start leads of the adjacent coils.

CONSTITUTION: The winding start leads 1a and 2a of the respective coils 1 and 2 of a multisectional winding coil are lead outside of the radial direction of the coils. The tip parts of the winding starts leads 1a and 2a are mutually jointed and the joint part 3 is insulated from the environment and positioned at the winding position of the winding start leads 1a and 2a of the adjacent coils 1 and 2. Therefore, the joint work and between the coils 1 and 2 of the respective sections and the insulation treatment of such joint part can be performed in the outside of the radial direction of the coils 1 and 2.
