A grain-oriented electrical steel sheet comprising: a base steel sheet having plural grooves on a surface; and a glass film formed on the surface of the base steel sheet, the content rate of forsterite in the glass film being 70% by volume or more, wherein an angle that a groove longitudinal direction makes with a direction orthogonal to a rolling direction and a sheet thickness direction of the base steel sheet is 0° to 40°, a width of the groove is 20 to 300 μm, a depth of the groove is 10 to 40 μm, intervals of the grooves in the rolling direction are 2 to 30 mm, and when, in the case of viewing a region including the grooves in a cross section orthogonal to the groove longitudinal direction, a point present on a profile line of the glass film and present at a highest location in the sheet thickness direction is defined as a peak point, a straight line passing through the peak point and parallel to a groove width direction orthogonal to the sheet thickness direction in the cross section is defined as a reference line, a point present on a boundary line between the glass film and the base steel sheet and present at a lowest location in the sheet thickness direction is defined as a deepest point, and a point present on the boundary line and present at the highest location in the sheet thickness direction in a region having the deepest point in a center and having a length of 2 μm in the groove width direction is defined as a shallowest point, and a relationship between a shortest distance A between the reference line and the deepest point and a shortest distance B between the reference line and the shallowest point satisfies Expression, 0.1 μ m ≤ A − B ≤ 5.0 μm a base steel sheet having plural grooves on a surface; and a glass film formed on the surface of the base steel sheet, the content rate of forsterite in the glass film being 70% by volume or more, wherein an angle that a groove longitudinal direction makes with a direction orthogonal to a rolling direction and a sheet thickness direction of the base steel sheet is 0° to 40°, a width of the groove is 20 to 300 μm, a depth of the groove is 10 to 40 μm, intervals of the grooves in the rolling direction are 2 to 30 mm, and when, in the case of viewing a region including the grooves in a cross section orthogonal to the groove longitudinal direction, a point present on a profile line of the glass film and present at a highest location in the sheet thickness direction is defined as a peak point, a straight line passing through the peak point and parallel to a groove width direction orthogonal to the sheet thickness direction in the cross section is defined as a reference line, a point present on a boundary line between the glass film and the base steel sheet and present at a lowest location in the sheet thickness direction is defined as a deepest point, and a point present on the boundary line and present at the highest location in the sheet thickness direction in a region having the deepest point in a center and having a length of 2 μm in the groove width direction is defined as a shallowest point, and a relationship between a shortest distance A between the reference line and the deepest point and a shortest distance B between the reference line and the shallowest point satisfies Expression, 0.1 μ m ≤ A − B ≤ 5.0 μm
