Abstract:
A laminated core according to an aspect of the present invention includes a plurality of electrical steel sheets stacked to each other; and a plurality of adhesion parts that are provided between the electrical steel sheets adjacent to each other in a stacking direction and adhere the electrical steel sheets to each other, in which, when viewed in the stacking direction, the plurality of adhesion parts are formed in a belt shape that extends in a first direction, the plurality of adhesion parts are arranged in a second direction orthogonal to the first direction, and an angle formed by the first direction and a rolling direction of the electrical steel sheet is 30° or more and 90° or less.
