Abstract
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. In a case where the steel sheet surface is seen from the sheet thickness direction, the steel sheet surface is provided with a groove group that is constituted by a plurality of the grooves arranged in a sheet width direction, the grooves, which constitute the groove group, are arranged in such a manner that adjacent grooves overlap each other on a projection plane perpendicular to the rolling direction, and a plurality of the groove groups are arranged with an interval in the rolling direction.
