GRAIN-ORIENTED ELECTRICAL STEEL SHEET AND METHOD FOR PRODUCING GRAIN-ORIENTED ELECTRICAL STEEL SHEET

A grain-oriented electrical steel sheet includes: a base steel sheet having a predetermined chemical composition; a glass coating provided on the surface of the base steel sheet; and a tension-applying insulation coating provided on the surface of the glass coating, in which linear thermal strains having a predetermined angle ϕ with respect to a transverse direction which is a direction orthogonal to a rolling direction are periodically formed on the surface of the tension-applying insulation coating at predetermined intervals along the rolling direction, a full width at half maximum F1 on the linear thermal strain and a full width at half maximum F2 at an intermediate position between the two linear thermal strains adjacent to each other satisfy 0.00 < (F1 - F2) / F2 ≤ 0.15, the width of the linear thermal strain is 10 µm or more and 300 µm or less, and in the base steel sheet, an orientation distribution angle γ around a rolling direction axis of secondary recrystallization grains, an orientation distribution angle α around an axis parallel to a normal direction, and an orientation distribution angle β around an axis perpendicular to each of the RD axis and the ND axis in units of ° satisfy 1.0 ≤ γ ≤ 8.0 and 0.0 ≤ (α2 + β2)0.5 ≤ 10.0.
