A stator for rotary electric machine, comprising: a stator core including an annular yoke and a plurality of magnetic pole portions disposed at an inner peripheral portion of the annular yoke at intervals in a circumferential direction of the annular yoke and projecting towards a centerline of the annular yoke, the magnetic pole portions each including a pole column and a magnetic pole piece having a magnetic surface, the pole column having one end integrally formed with the annular yoke and the other end on which the magnetic pole piece is integrally disposed; a plurality of winding portions formed of winding conductors wound around the plurality of magnetic pole portions of the stator core; and a slot insulator formed of an insulating resin, attached to the stator core for electrically insulating the stator core from the winding portions, and including at one axial end portion thereof connecting wire hooks capable of engaging with connecting wires formed of a part of the winding conductor extending from each of the winding portions, characterized in that: each of the connecting wire hooks is integrally formed with the axial end portion of the slot insulator such that the connecting wire hooks are located at least partially within a first extended space that is defined by extending in the axial direction a slot space where the winding portion is located, and such that, assuming that a second extended space is defined by extending toward the yoke a slot opening space formed between two adjacent magnetic pole pieces covered with the slot insulator and a third extended space is defined by extending the second extended space in the axial direction, the connecting wire hook is not located within the third extended space. a stator core including an annular yoke and a plurality of magnetic pole portions disposed at an inner peripheral portion of the annular yoke at intervals in a circumferential direction of the annular yoke and projecting towards a centerline of the annular yoke, the magnetic pole portions each including a pole column and a magnetic pole piece having a magnetic surface, the pole column having one end integrally formed with the annular yoke and the other end on which the magnetic pole piece is integrally disposed; a plurality of winding portions formed of winding conductors wound around the plurality of magnetic pole portions of the stator core; and a slot insulator formed of an insulating resin, attached to the stator core for electrically insulating the stator core from the winding portions, and including at one axial end portion thereof connecting wire hooks capable of engaging with connecting wires formed of a part of the winding conductor extending from each of the winding portions, characterized in that: each of the connecting wire hooks is integrally formed with the axial end portion of the slot insulator such that the connecting wire hooks are located at least partially within a first extended space that is defined by extending in the axial direction a slot space where the winding portion is located, and such that, assuming that a second extended space is defined by extending toward the yoke a slot opening space formed between two adjacent magnetic pole pieces covered with the slot insulator and a third extended space is defined by extending the second extended space in the axial direction, the connecting wire hook is not located within the third extended space.
