This grain-oriented electromagnetic steel sheet is provided with a steel layer and an insulating coating film that is arranged directly on the steel layer. The steel layer contains, as chemical components in mass%, 2.9-4.0% of Si, 2.0-4.0% of Mn, 0-0.20% of Sn and 0-0.20% of Sb. With respect to the steel layer, the silicon content and the manganese content satisfy, in mass%, 1.2% ≤ Si - 0.5 × Mn ≤ 2.0%, and the tin content and the antimony content satisfy, in mass%, 0.005% ≤ Sn + Sb ≤ 0.20%. |
