A stator for an electric rotating machine includes a stator coil that is formed of a plurality of electric wire segments each of which is comprised of an electric conductor and an insulating coat covering the electric conductor. The electric wire segments include a joined pair of first and second electric wire segments. Each of the first and second electric wire segments has an end portion of a first predetermined length where the electric conductor is not covered by the insulating coat. The end portions of the first and second electric wire segments are joined together. For each of the first and second electric wire segments, the insulating coat has, at its boundary with the end portion of the electric wire segment, a peeled portion of a second predetermined length which has a distal end peeled from the electric conductor and a proximal end remaining attached to the electric conductor.
