Grain Oriented Electromagnetic Steel Sheet And Production Method Therefor

Abstract: This grain-oriented electromagnetic steel sheet comprises a base steel sheet and an insulating coating film disposed directly on the base steel sheet. When this grain-oriented electromagnetic steel sheet is cut along a direction parallel with the sheet thickness direction and perpendicular to the sheet width direction and the cut surface is examined, the average determined Fe content Ibase of an inner-layer region of the base steel sheet and the average determined Fe content Icoating of an inner-layer region of the insulating coating film satisfy 0.010=Icoating/Ibase=0.50.
