Armature for rotary electric machine

An armature for a rotary electric machine comprising:

• a core that includes teeth that are respectively arranged to extend radially at a predetermined pitch in a circumferential direction;
• and
• edgewise coils that are configured by winding a rectangular conductor wire that is coated with insulation for a plurality of turns into an edgewise winding,
• wherein:
• each of the edgewise coils includes rectilinear portions and coil end portions that are arranged radially, each of the rectilinear portions and the coil end portions being linked by bent portions;
• the rectilinear portions are arranged radially on circumferential side portions of the teeth to be gradually further away from a central axis of a respective one of the teeth from a tip end of the respective one of the teeth toward a root of the respective one of the teeth;
• and
• radially adjacent portions of the rectangular conductor wire are configured such that bulging portions that arise due to compressive stresses resulting from bending at inner peripheral side portions of the bent portions do not face each other.
