PROBLEM TO BE SOLVED: To enhance dimensional accuracy of each split core configuration piece during press work. ! SOLUTION: A laminated core 32 is divided into a plurality of split cores 38, which are arranged so that the coupling parts 50 formed at the proximal ends of teeth 48 have an annular shape. A pair of abutting parts 50A abutting each other at adjacent coupling parts 50 form the split part 52 of adjacent coupling parts 50, and each split part 52 is inclining in the radial direction of a dynamo-electric machine. A fitting recess 54 and a fitting protrusion 56 are formed in the pair of abutting parts 50A, and the adjacent coupling parts 50 are coupled when the fitting recess 54 and fitting protrusion 56 are fitted. !
