Grain-oriented electrical steel sheet and method for manufacturing same

A grain-oriented electrical steel sheet comprising:

• a base steel sheet;
• a glass coating formed on the base steel sheet;
• and
• a tension-applied insulation coating formed on the glass coating,
• wherein the base steel sheet has the chemical composition, by mass %:
• C:
• 0.010% or less,
• Si:
• 3.00% to 4.00%,
• Mn:
• 0.01% to 0.50%,
• N:
• 0.010% or less,
• Sol. Al:
• 0.020% or less,
• P:
• 0.030% or less,
• S:
• 0.010% or less,
• Sn:
• 0% to 0.50%,
• Cu:
• 0% to 0.50%,
• Cr:
• 0% to 0.50%,
• Se:
• 0% to 0.020%,
• Sb:
• 0% to 0.500%,
• Mo:
• 0% to 0.10%, and
• a remainder of Fe and impurities,
• wherein, on a front surface of the base steel sheet, a plurality of linear strains that extend continuously or intermittently in a direction intersecting with a rolling direction are present,
• intervals p in the rolling direction of the plurality of linear strains adjacent to each other are 3.0 to 9.0 mm,
• widths of the linear strains are 10 to 250 μm, and
• in an X-ray topographic spectrum in a range of 1.50 mm in the rolling direction including the linear strain at a center, that is obtained from an X-ray topographic image of the front surface, a full width at half maximum of a peak of the X-ray topographic spectrum including a maximum value of a spectral intensity is 0.02 mm or more and 0.10 mm or less.
