PROBLEM TO BE SOLVED: To obtain a laminated core of a dynamo-electric machine in which the man hours required for forming the laminated core can be reduced, and to provide a manufacturing method therefor, and the armature of the dynamo-electric machine.SOLUTION: Core constituent pieces 12 are arranged annularly in the circumferential direction (arrow C1 direction and arrow C2 direction) of a dynamo-electric machine, and a positive direction core sheet 14 is configured by fitting fitting protrusions 24 and fitting recesses 26 both formed in a core annular part constituent part 22. Between one fitting protrusion 24 and one fitting recess 26 adjoining in the circumferential direction (arrow C1 direction and arrow C2 direction) of the dynamo-electric machine, a predetermined clearance is provided in the circumferential direction (arrow C1 direction and arrow C2 direction) of the dynamo-electric machine. Furthermore, a laminated core 10 of the dynamo-electric machine is configured by laminating the positive direction core sheets 14. |
