Zusammenfassung:	The present invention relates to a grain-oriented electrical steel sheet and a manufacturing method therefor, wherein the method comprises heating a steel slab, hot rolling, cold rolling, decarbonizing, nitride annealing, and final high temperature annealing which are successively performed. The present invention provides the manufacturing method for the grain-oriented electrical steel sheet, which controls the temperatures for the decarbonizing and nitride annealing to be maintained at 850-900°C, and a dew point inside the decarbonizing and nitride annealing furnace to be maintained at 40-70°C; and the grain-oriented electrical steel sheet manufactured by the method.
