Abstract
A stator includes a core fixed to a case of a rotary electric machine, and a plurality of winding wire coils that are wound on the core and that form a coil end protruded in the axial direction of the core. The two winding wire coils have a first and second conducting wires that are exposed in a distal end of each of the two coils. The stator includes: a joint in which the first and second wires are joined together at the coil end and in which proximal portions of the two coils approach each other with an acute angle therebetween so that the first and second wires lie on each other; and an insulating coat formed to enclose the joint with an insulating material that is coated entirely over peripheries of the two coils in their circumferential directions while filling a space across which the proximal portions form the acute angle. A rotary electric machine includes the stator, the case and a rotor.
