Abstract
This grain-oriented electrical steel sheet includes a plurality of magnetic domain control treatment lines extending in a direction intersecting a rolling direction on a surface, in a case where a square evaluation region having a side length of 50 mm and a side parallel to the rolling direction is set on the surface, and further, imaginary lines parallel to the rolling direction and having a length of 50 mm are set inside the evaluation region at intervals of 5 mm in a direction perpendicular to the rolling direction, in at least one of the imaginary lines, among the plurality of intersection points of the imaginary line and the plurality of magnetic domain control treatment lines, the absolute maximum value of an interval between adjacent intersection points in the rolling direction is more than 20 mm, and the average value of spacings of magnetic domain walls measured along the imaginary line is 600 µm or less, and the plurality of magnetic domain control treatment lines are tensile stress introduction lines in which a tensile stress of 40 MPa or more is introduced.
