ORIENTED ELECTROMAGNETIC STEEL SHEET

摘要

This oriented electromagnetic steel sheet is provided with a steel sheet having a surface which has, formed therein, grooves which extend in a direction intersecting the rolling direction, and which have a depth direction that becomes the sheet thickness direction. When viewed from the sheet thickness direction, the surface of the steel sheet has groove groups formed from a plurality of the grooves arranged in the sheet width direction. The grooves which form the groove groups are arranged so as to overlap adjacent grooves on a projection plane orthogonal to the rolling direction. A plurality of the groove groups are arranged in the rolling direction with an interval therebetween.
