Abstract

A manufacturing method of a stator includes: performing winding and laying a connecting wire. The performing winding and the laying the connecting wire are alternately repeated. In the performing winding, the winding to be in contact with portions of the insulators that are located opposite to the back yokes is wound such that a distal end of the winding nozzle is caused to pass through an inside of the recessed insulator portion, while the winding led out from the distal end of the winding nozzle is being laid over a stepped portion.
