摘要:
A laminated core includes: a plurality of electrical steel sheets stacked in a thickness direction, wherein the electrical steel sheet includes an annular core back part and a plurality of tooth parts protruding from the core back part toward a radial direction and arranged at intervals in a circumferential direction of the core back part, and wherein among the plurality of electrical steel sheets, the tooth parts of the electrical steel sheets located at one side on the outside in a stacking direction are adhered to each other by an adhesion part provided between the tooth parts adjacent to each other in the stacking direction, the tooth parts of the electrical steel sheets located at the other side on the outside in the stacking direction are adhered to each other by an adhesion part provided between the tooth parts adjacent to each other in the stacking direction, and the tooth parts of the electrical steel sheets located at a center part in the stacking direction are not adhered to each other.
