The present invention relates to manufacturing a grain-oriented electric steel sheet. The present invention relates to a method for manufacturing a grain-oriented electric steel sheet having superior magnetic property and to a grain-oriented electric steel sheet manufactured by the method, wherein the method comprises heating a slab comprising 2.0 to 4.5 weight % of Si, 0.001 to 0.10 weight % of C, 0.010 weight % or lower of Al, 0.08 weight % or lower of Mn, 0.005 weight % or lower of N, 0.002 to 0.050 weight % of S, the remainder being Fe and other unavoidable impurities, performing hot-rolling of the heated slab, performing cold-rolling one time or twice or more times including an intermediate annealing, performing decarbonization and re-crystallizing annealing, and performing secondary re-crystallizing annealing. |
