Abstract
Provided are a rotary-electric-machine stator coil, a rotary-electric-machine stator having the same, and a rotary electric machine having the same, capable of improving a bonding strength and insulation reliability of a conductor bonding portion. A rotary-electric-machine stator coil includes: a conductorhaving a bonding portionbonded to other conductors; and a bonding memberhaving a melting point lower than a melting point of the conductor, wherein a tip of the bonding portion has an alloy layerformed of an alloy of the conductor and the bonding member, and a root of the bonding portion is electrically connected by the bonding member.
