PROBLEM TO BE SOLVED: To ensure simple and accurate assembly without the need for using an assembly jig, or the like. SOLUTION: A stator core 1 includes core-backs 7a and 7b, extending in the circumferential direction, many teeth 3a and 3b that extend radially from the core-backs 7a and 7b and are disposed at intervals in the circumferential direction, and many tabular core units 9A and 9B, laminated in the plate thickness direction by shifting the phase of the teeth 3a and 3b. On the core units 9B adjacent in the lamination direction, step portions 11 are provided for abutting against other core units 9A in the circumferential direction and radially, with the core-backs 7a and 7b overlapping each other.
