<p>Provided is an armature core capable of, when welding teeth having a plurality of magnetic bodies and a yoke, reducing a welding process. The armature core (1) comprises a back yoke (11) and teeth (12). The teeth (12) include a plurality of magnetic plates (121) laminated along a lamination direction (D2). The back yoke (11) has openings (112) into which the teeth (12) are inserted. The openings (112) pass through a pair of surfaces (11a, 11b) of the back yoke (11). The boundary edges of adjacent magnetic plates and the surface (11c) forming the opening (112) are close to each other, and the back yoke (11) and the magnetic plates (121) are mutually welded at an exposed portion of either one of the pair of surfaces (11a, 11b).</p> |
