摘要：
A grain oriented electrical steel sheet includes forsterite film on a surface of base steel sheet and a selenium-concentrated portion in at least one of the forsterite film and an interface between the forsterite film and the base steel sheet by a presence ratio expressed as area-occupying ratio of the Se-concentrated portion, of at least 2%, per 10000 μm2 of the surface of the base steel sheet, which has been subjected to magnetic domain refinement treatment by electron beam irradiation.
