Abstract

This grain-oriented electrical steel sheet is a grain-oriented electrical steel sheet including a plurality of magnetic domain control treatment lines on a surface thereof, in which in a case where a rectangular evaluation region in which a length of a side parallel to a rolling direction of the grain-oriented electrical steel sheet is 50 mm and a length of a side parallel to a transverse direction of the grain-oriented electrical steel sheet is 100 mm is set in the grain-oriented electrical steel sheet, and further, imaginary lines parallel to the transverse direction and having a length of 100 mm are set inside the evaluation region at intervals of 5 mm in a direction parallel to the rolling direction, in at least one of the imaginary lines, the standard deviation of an interval between magnetic domain control points that are intersection points of the imaginary line and the magnetic domain control treatment line is 1.25 mm or more, and an average value |β<L>| of absolute values of β angles measured between two magnetic domain control points at which the interval becomes an absolute maximum value D<L> is 1.5° or more.
