Abstract:
A stator of an electric rotary machine includes a first abutting portion and a second abutting portion. The first abutting portion and the second abutting portion are welded by laser welding in a state where the abutting portions abut against each other, and the first abutting portion and the second abutting portion include bonding surfaces which are bonded to each other. In the axial direction, a height from an insulating cover film to the bonding surface in one abutting portion is greater than a height from an insulating cover film to the bonding surface in the other abutting portion, and in a radial direction, a protruding distance from the insulating cover film to the bonding surface in the one abutting portion is greater than a retraction distance from the insulating cover film to the bonding surface in the other abutting portion.
