PROBLEM TO BE SOLVED: To provide an armature of a dynamo-electric machine which allows for enhancement in the space factor even with a small size, and to provide a dynamo-electric machine, and a method of manufacturing the armature of a dynamo-electric machine.SOLUTION: An armature 10 includes an iron core 1 formed by annularly arranging a plurality of split iron cores 3, each having a split yoke 32 and a tooth 31 extending therefrom, and a coil 2 disposed across the plurality of teeth 31 of the iron core 1 on the inside of the slot 5 thereof. One split iron core 3 has a first tooth 31a and a second tooth 32b extending from both ends of the split yoke 32 in the circumferential direction. First tooth 31a of one of two adjacent split iron cores 3 and a first tooth attachment part 32a of the split yoke, and second tooth 31b of the other split iron core 3, and a second tooth attachment part 32b of the split yoke 32, are superposed in the axial direction of the iron core 1. |
