Stator for rotary electric machine, rotary electric machine, and method for manufacturing stator for rotary electric machine

A stator for rotary electric machine, comprising a stator core and a stator coil wound around teeth of the stator core, wherein

• the stator core includes
• an outer core which is an annular back yoke portion, and
• an inner core having the plurality of teeth radially arranged, and having a connection portion via which inner-circumferential-side ends of the teeth adjacent to each other in a circumferential direction are connected to each other in the circumferential direction, the inner core being fitted to an inner side of the outer core,
• slots are each formed between the teeth adjacent to each other in the circumferential direction, and slot accommodation portions of divisional coils each of which is a minimum unit composing the stator coil are inserted in each slot so as to be arranged side by side in a radial direction,
• a first terminal wire of one of the divisional coils and a second terminal wire of another one of the divisional coils extend toward the same side in the axial direction from the two slot accommodation portions adjacently arranged on an entrance side or a bottom side of each slot,
• a first terminal portion of the first terminal wire and a second terminal portion of the second terminal wire are arranged, side by side in the radial direction of the stator, on an upper side in the axial direction of the stator core, so as to be directed upward in the axial direction, and
• an end of the first terminal portion and an end of the second terminal portion are joined to each other by a joining part, and at least one of the first terminal portion and the second terminal portion leading to the joining part has an engagement portion for positioning the first terminal portion and the second terminal portion with each other in the circumferential direction and the radial direction.
