Abstract

The present invention addresses the problem of providing a grain oriented electrical steel sheet exhibiting low hysteresis loss and coercive force wherein an increase in hysteresis loss due to laser irradiation or electron beam irradiation which has been a conventional concern is effectively inhibited. A grain oriented electrical steel sheet having closure domain regions (X) formed so as to divide the magnetic domains in the rolling direction from one width side edge to the other width side edge of the steel sheet wherein the relationship of the following equation (1) is satisfied: (500t 80)×s+230=w= (500t 80)×s+330 where t represents the sheet thickness in millimeters; w represents the smaller value in micrometers obtained by measuring the widths of the aforementioned regions (X) from the front and rear surfaces of the steel sheet by means of the Bitter method; and s represents the average number of the regions (X) that are present within one crystal grain.
