Abstract
Provided is a stator of a rotary electric machine in which a bonding portion of ends of coil segments is formed at a coil end of the stator without being inflated toward the opposite side to a stator core, and the coil end can be minimized in an axial direction. The stator of the rotary electric machine includes a stator core () having a plurality of slots and a coil segment () which is disposed in the stator core to form a stator winding (). The ends of the coil segments are overlapped in the axial direction, and bonded through the bonding portion. The bonding portion is formed in a shape such that the bonding portion is melted and flows down from the end () of the coil segment on the opposite side to the stator core toward the end () of the coil segment on a side near the stator core.
