Abstract

See full text

Provided is a grain-oriented electrical steel sheet including a steel sheet having a steel sheet surface in which a groove, which extends in a direction intersecting a rolling direction and of which a groove depth direction matches a sheet thickness direction, is formed. An average depth D of the groove is greater than 10 μm and equal to or less than 40 μm in a case where the groove is seen on a groove-width-direction cross-section that is perpendicular to a groove extension direction, when a center of the groove in the groove width direction is defined as a groove width center, a deepest portion of the groove deviates from the groove width center toward one side in the groove width direction, and a cross-sectional shape of the groove is asymmetric with respect to the groove width center as a reference in the groove width direction.
