摘要:
A laminated core includes a plurality of electrical steel sheets stacked on each other, and an adhesion part which is provided between the electrical steel sheets adjacent to each other in a stacking direction and adheres the electrical steel sheets to each other, in which the electrical steel sheet include an annular core back part, and a plurality of tooth parts which extend from the core back part in a radial direction of the core back part and are disposed at intervals in a circumferential direction of the core back part, an adhesion region in which the adhesion part is provided is formed in the core back part of the electrical steel sheet, and the adhesion region extends in a direction along a magnetic flux passing through a region of the electrical steel sheet in contact with the adhesion region.
