Abstract
In a multiphase armature winding provided in an armature that constitutes a rotating electric machine and that is configured by conductive wire material, the conductive wire material for each phase includes an assembly of strands having a conductor and an inner insulating layer of insulating material surrounding the conductor, and an outer insulating layer of insulating material surrounding the assembly of strands. The outer insulating layer is peeled off at an end of the conductive wire material. A tip of the conductive wire material at the peeled portion of the outer insulating layer is joined by welding or crimping to form a joint portion. At least a portion other than the joint portion, in the conductive wire material at the peeled portion of the outer insulating layer, is varnished.
