Abstract
A stator for a rotary electric machine includes a stator core, three-phase coils, and a neutral point connection conductor. The three-phase coils are wound around the stator core. The neutral point connection conductor is connected to each of the three-phase coils. The neutral point connection conductor includes a linear conductor that is bent. The linear conductor includes two end portions and an overlapping portion in which the conductor is folded back and doubled up. One of the two end portions is connected to one-phase coil of the three-phase coils. The other of the two end portions is connected to another-phase coil of the three-phase coils. The overlapping portion is connected to the remaining-phase coil of the three-phase coils.
