C: 0.002~0.10mass%, Si: 2.0~8.0mass% and Mn: hot rolling the steel to (鋼) material containing 0.005~1.0mass% without a hot-rolled sheet and hot rolled sheet annealing, or conducted after performing the , once or by intermediate annealing rolling two or more times cold place between the after performing the decarburization annealing doubling as the end plate the primary recrystallization annealing to the cold-rolled sheet, and the thickness, by applying an annealing separator to the steel sheet surface to finish annealing in the method for producing a grain-oriented electrical (電磁) steel plate consisting of a series of processes, when the period of the decarburization annealing of 200~700 ℃ be rapidly heated to above 50 ℃ / s, at which temperature of between 1~ 250~600 ℃ by holding for 10 seconds, low (低) core and also producing a grain-oriented electrical steel sheet is less variation in the iron loss (鐵 損) value.
