PROBLEM TO BE SOLVED: To provide the structure of a stator iron core structure for a dynamo-electric machine, which enables easy and stable junction of divided yokes and can reduce the magnetic resistance of a steel plate at a section adjacent to a butting part and has a junction structure, capable of improving iron loss property by uniformizing the magnetic flux in a yoke, in a stator iron core structure which consists of a plurality of teeth made by stacking steel plates and a roughly cylindrical yoke, and divides a yoke part in the circumferential direction into plural pieces and re-joins them together. SOLUTION: The butting positions of the steel plates, opposed in the circumferential direction of the yoke part, are slid in tiers in stacking direction, and this arrangement is repeated in the stacking direction; thus a lap is made to a steel plate which adjoins it in the stacking direction and faces it in the circumferential direction, and divided yokes are butted so that the butting positions of opposed steel plates come into a saw-teeth shape in the stacking direction, in the section of the junction of the stacked steel plates.
