Abstract
In a grain-oriented electrical steel sheet including: a steel substrate; a forsterite base film; and an insulating coating, critical damage shear stress τ between the forsterite base film and the steel substrate is 50 MPa or more and 200 MPa or less. Thus, a grain-oriented electrical steel sheet having excellent insulation property, stacking factor, and magnetic property is provided without coating damage even when magnetic domain refining treatment by thermal strain is performed.
