PROBLEM TO BE SOLVED: To prevent misalignment of a core segment by equipping a coil that is wound around the core segment via an insulator for insulating a coil winding part, performing connection at a core segment connection part as a stator, and locating the insulator outside the connection part of the core segment. SOLUTION: Adjacent core segments 1 and 2 where insulators 3 and 4 are fitted are engaged by a connection recess 1b and a connection protrusion 2a. The connection protrusion 2a of the adjacent core segments 2 is retained by a core retention part 3b of the insulator 3 for retaining the lamination direction of the core segments 2, and the direction of the lamination of the entire core segment is determined in the winding preprocess of a coil 5. In a process for rounding the core segments 1 and 2, the connection protrusion 2a of the adjacent core segments 2 is retained by the core retention part 3b of the insulator 3, and the connection recess 1b of the core segment 1 is retained, thus forming structure where there is no misalignment of the core segments in the direction of lamination.
