摘要：
The present invention provides oriented magnetic steel plate with excellent coating adhesion, in particular coating edge peeling resistance, that is, oriented magnetic steel plate with excellent coating adhesion containing, by mass %, Si: 1.8 to 7% and having a primary coating having forsterite as its main ingredient on its surface, said oriented magnetic steel plate characterized in that said primary coating contains one or more of Ce, La, Pr, Nd, Sc, and Y in an areal weight per side of 0.001 to 1000 mg/m2; characterized in that said primary coating contains Ti in an areal weight per side of 1 to 800 mg/m2; and characterized in that said primary coating contains one or more of Sr, Ca, and Ba in an areal weight per side of 0.01 to 100 mg/m2.
