PROBLEM TO BE SOLVED: To provide an armature core for reducing welding processes in welding teeth having a plurality of magnetic bodies and yokes. SOLUTION: The armature core 1 is provided with a back yoke 11 and teeth 12. The teeth 12 is provided with a plurality of magnetic plates 121 that are laminated along the lamination direction D2. The back yoke 11 is provided with a hole 112 into which the teeth 12 is fitted. The hole 112 penetrates through the surfaces 11a, 11b of the back yoke 11. The edges of boundaries in the adjacent magnetic plates and the surface 11c that forms the hole 112 are close to each other and are mutually welded at portions that are exposed on the surface 11a side or surface 11b side, between the back yoke 11 and a plurality of the magnetic plates 121.
