摘要: An electrical steel sheet includes an annular body. At least one of a plurality of adhesion layers (41) is a first adhesion layer. In one of two electrical steel sheets sandwiching the first adhesion layer in a stacking direction, when an imaginary axis intersecting with a central axis of the annular body and extending in an easy-magnetization direction is defined as an L-axis, an imaginary axis intersecting with the central axis and intersecting with the L-axis is defined as a C-axis, and the electrical steel sheet is partitioned into a plurality of sections (S) in a circumferential direction of the annular body by the L-axis and the C-axis, at least one of the plurality of sections (S) is a first section. In the first section, an area of the first adhesion layer in a first portion (P1) of the electrical steel sheet where a main magnetic flux is generated in the L-axis direction is smaller than an area of the first adhesion layer in a second portion (P2) of the electrical steel sheet where the main magnetic flux is generated in the C-axis direction.
