PROBLEM TO BE SOLVED: To provide a stator core which can improve its production efficiency. SOLUTION: In a stator core, where a plurality of split cores 11, which have each a yoke component 13 and a winding spool 15, are coupled with one another and can be coupled with one another in annular form so that each winding spool 15 may be positioned inside, the first coupling 21 and the second coupling 22 used for coupling with adjacent other split core are formed in the yoke component 13, and the first coupling 21 is constituted of a protrusion whose outline is circular, and the second coupling 22 is constituted of a recess whose outline is in roughly the same form as the first coupling 21, and a crest-form engaging projection 23 is formed at one part of the protrusion, in the first coupling 21, and in the second coupling 22, the first depression 31, which engages with the engaging projection 23 when the plurality of split cores 11 are band-shaped, and the second depression 32, which engages with the engaging projection 23, when the plurality of split cores 11 are annular, are formed.
