PROBLEM TO BE SOLVED: To provide a winding method which never causes winding callapse with effectively preventing layer short. SOLUTION: A wire 5 is wound in layers round a bobbin from its base end to final end to form a coil 9. This method comprises forming a winding block a having a step in the running direction of the winding on the base end, forming a winding block b having a step on the upper face of that step, alternately forming winding-up blocks c, c1,..., cα and winding-down blocks d, d1,..., dα alternately overlapped at the steps 13, 14, and forming a final end winding block covering all the step 14 of the block dα and its own lower layer at the final end of the coil 9. The winding is made such that the wires 5 of the upper layer extend along groves 10 between the wires 5 of the lower layer. |
