By mass%, C: 0.001~0.10%, Si: 1.0~5.0%, Mn: 0.01~0.5%, S and / or Se: 0.005~0.040%, sol.Al: 0.003~0.050%, and N: 0.0010~0.020 % and hot the river (鋼) slab rolling containing, once or to the final sheet thickness by twice or more cold rolling so as to sandwich the intermediate annealing, and then subjected to primary recrystallization annealing, applying an annealing separating agent in the method for producing a grain-oriented electrical (電磁) performing finish annealing the steel sheet, rapidly between 550~700 ℃ in a heating process for the primary recrystallization annealing to the average temperature increase (昇溫) speed 40~200 ℃ / s heating and also together, by maintaining 1~10 seconds at a rate of temperature increase below 10 ℃ / s according to any of the temperature range between 250 ℃ ~550 ℃, to achieve the miniaturization of the secondary recrystallized grains, achieved stably a low iron loss (低 鐵 損) obtain a grain-oriented electrical steel sheet.
