PROBLEM TO BE SOLVED: To manufacture a dynamoelectric machine stator which has a high space factor of a winding, while a large number of exclusive jigs supporting a plurality of divided cores all through a manufacturing process are not necessary. SOLUTION: A plurality of divided cores 1, are arranged anularly, so as to make their magnet wire winding parts 1b face inward and to provide gaps between yoke forming parts 1a of the respective two adjacent divided cores 1 to form an annular divided core row 2 for magnet wire winding. A nozzle 4 of a wire winder 3 is placed inside the annular divided core row 2 to wind magnet wires on the magnet wire winding parts 1b of the divided cores 1, etc. After the magnet wires are wound on all the winding parts 1b, of the plurality of the divided cores 1, they are made to come closer to a center of the annular divided core row 2 so as to reduce a diameter of the core row 2, and to bring end surfaces 1g and 1g of the yoke forming parts 1a and 1a of the two adjacent divided cores 1 and 1 into contact with each other.
