A rotating electric machine in which, in welding a stator core and a case together, thermal damage to an insulation film due to the welding is suppressed. The rotating electric machine has the case (10) and the stator core (20). The stator core (20) has teeth (21) and a back yoke (22). Recesses (221) open to the side opposite a rotating shaft (P) are arranged in the outer peripheral surface (220) of the back yoke (22) such that each of the recesses (221) corresponds to each of the teeth (21). The case (10) and the stator core (20) are welded and fixed together at a position between each of two recesses (221) adjacent to each other in the direction of a circumference about the rotating axis (P). The minimum distance between the root and recess (221) of each of the teeth (21) is smaller than the width in the radial direction of the back yoke.
