摘要
Provided is a method for producing an oriented electrical steel sheet with an ultra-low iron loss. The method for producing an oriented electrical steel sheet according to the present invention comprises: a step of preparing an oriented electrical steel sheet; and a step of forming a ceramic coating layer by subjecting a gas-phase ceramic precursor to a contact reaction in a plasma state using the atmospheric pressure plasma CVD (APP-CVD) process, on a part of or the entire one or both surfaces of the electrical steel sheet.
