A grain-oriented electrical steel sheet comprising: a base steel sheet; a primary film formed on a surface of the base steel sheet; and a tension insulation coating formed on a surface of the primary film, wherein a magnetic domain control is performed by irradiating the tension insulation coating with a laser from above, when a strip-like sample having a length of 300 mm in a direction parallel to a rolling direction of the grain-oriented electrical steel sheet and a length of 60 mm in a direction parallel to a transverse direction is extracted from the grain-oriented electrical steel sheet, a range from a surface of the tension insulation coating to a depth position of 5 μm to 50 μm toward the base steel sheet side from an interface between the base steel sheet and the primary film is removed by pickling at least one surface of the sample, and a warpage amount of one end of the sample is thereafter measured by vertically placing the sample in a state in which 30 mm of an opposite end of the sample in a longitudinal direction is nipped by a clamp, the warpage amount satisfies the following expressions A and B. 15000 μ ⁢ m ≤ S A − S C ≤ 35000 μm 900 μ ⁢ m ≤ S B + S C ≤ 14000 μm Here, S A, S B, and S C are described below. S A: a warpage amount of the grain-oriented electrical steel sheet in the unit of μm when only one surface subjected to laser irradiation is pickled, S B: a warpage amount of the grain-oriented electrical steel sheet in the unit of μm when only one surface on a side opposite to the side subjected to laser irradiation is pickled, and S C: a warpage amount of the grain-oriented electrical steel sheet in the unit of μm when both surfaces are pickled, here, warpage in the same direction as that of the pickled surface during measurement of S A and S B is expressed as a positive value, and warpage in S C in the same direction as that of S A is expressed as a positive value, wherein a value d t /d p obtained by dividing an average thickness d t of the tension insulation coating in the unit of μm by an average thickness d p of the primary film in the unit of μm is 0.1 or higher and 1.5 or lower. a base steel sheet; a primary film formed on a surface of the base steel sheet; and a tension insulation coating formed on a surface of the primary film, wherein a magnetic domain control is performed by irradiating the tension insulation coating with a laser from above, when a strip-like sample having a length of 300 mm in a direction parallel to a rolling direction of the grain-oriented electrical steel sheet and a length of 60 mm in a direction parallel to a transverse direction is extracted from the grain-oriented electrical steel sheet, a range from a surface of the tension insulation coating to a depth position of 5 μm to 50 μm toward the base steel sheet side from an interface between the base steel sheet and the primary film is removed by pickling at least one surface of the sample, and a warpage amount of one end of the sample is thereafter measured by vertically placing the sample in a state in which 30 mm of an opposite end of the sample in a longitudinal direction is nipped by a clamp, the warpage amount satisfies the following expressions A and B. 15000 μ ⁢ m ≤ S A − S C ≤ 35000 μm 900 μ ⁢ m ≤ S B + S C ≤ 14000 μm Here, S A, S B, and S C are described below.
