Provided is a grain-oriented electrical steel sheet which gives a transformer excellent in terms of iron loss and building factor and in which the tensile-strength coating film is inhibited from being damaged. The grain-oriented electrical steel sheet, which includes a tensile-strength coating film, has a surface current of 0.15 A or less, has a plurality of linear strains formed therein and extending in a direction crossing the rolling direction, the plurality of linear strains having a rolling-direction line spacing of 15 mm or less, and has, formed in the strain parts, closure domains that have a sheet-thickness-direction length d of 65 µm or greater and a rolling-direction length w of 250 µm or less. |
