Abstract: A method for manufacturing grain-oriented electrical steel sheet includes: manufacturing a steel slab having at least one of 2 wt % to 7 wt % of Si, 0.03 wt % to 0.10 wt % of Sn, and 0.01 wt % to 0.05 wt % of Sb; hot-rolling the steel slab to produce a hot-rolled sheet; cold-rolling the hot-rolled sheet to produce a cold-rolled sheet; primary recrystallization-annealing the cold-rolled sheet; applying an annealing separator to the primary recrystallization-annealed cold-rolled sheet and drying the same; and secondary recrystallization-annealing the cold-rolled sheet on which the annealing separator is applied. The primary recrystallization-annealing is performed so that the thickness of an oxide layer formed on the surface of the cold-rolled sheet is 0.5 ?m to 2.5 ?m, and the oxygen amount of the oxide layer is 600 ppm or more after the primary recrystallization-annealing, and in which a forsterite (Mg2SiO4) film can be removed in the secondary recrystallization-annealing.
