The present invention provides a grain-oriented electrical steel sheet that is excellent in film adhesion, particularly film frame peelability, and contains, by mass, Si: 1.8 to 7% and has a forsterite as a main component on the surface. In the grain-oriented electrical steel sheet having a coating, the basis weight of one or more of Ce, La, Pr, Nd, Sc, and Y in the primary coating is 0.001 to 1000 mg / m 2 per side. The grain-oriented electrical steel sheet having excellent film adhesion, characterized in that the primary coating contains 1 to 800 mg / m 2 of Ti basis weight per side, and further, Sr, Ca, Ba in the primary coating One type or two or more types are contained in a basis weight of 0.01 to 100 mg / m 2 per side. |
