Abstract

Provided is a grain oriented electrical steel sheet having a linear groove forming an angle of 45° or less with the direction perpendicular to the direction of rolling wherein a grain oriented electrical steel sheet having low iron loss characteristics on which a magnetic domain subdivision treatment by chemical means is used is provided by setting the incidence of microparticles having a length of 1 mm or less in the rolling direction in a bottom part of the groove to 10% or less (also including cases in which microparticles are not present) providing a forsterite coating in which the Mg weight per side of the steel sheet is at least 0.6 g/m<sup>2</sup> in the groove and setting the angle (<i>ß</i> angle) between a rolling surface and the <100> axis of a secondary recrystallized grain oriented in the rolling direction of the steel sheet to an average value of 3° or less.
