Stacked Iron Core And Manufacturing Method Of Stacked Iron Core

Abstract: 1 < Ra(D)/Ra(S) ? 12 is satisfied in each of at least one pair of block opposing end faces (for example, a pair of block opposing end faces (111a, 111i)). Here, Ra(D) is the surface roughness of the block opposing end face in the stacking direction. Ra(S) is the surface roughness in the main magnetic flux direction (or rolling direction) of the plate surface of a steel plate having an end face that configures a part of the block opposing end face.
