Grain-oriented electrical steel sheet and method for forming intermediate layer and insulating coating included in grain-oriented electrical steel sheet

Abstract

Disclosed are: a grain-oriented electrical steel sheet including: a base steel sheet; an intermediate layer disposed on a surface of the base steel sheet; and an insulating coating disposed on a surface of the intermediate layer, wherein the intermediate layer has an average thickness of 20 to 200 nm, includes one or two or more selected from a group consisting of V, Mo, W, and Zr, and includes one or two or more selected from a group consisting of phosphorus; fluorine; and nitrogen and oxygen; and a method for forming the intermediate layer and the insulating coating included in the grain-oriented electrical steel sheet.
