<p>An oriented electrical steel sheet and a method for manufacturing the oriented electrical steel sheet are disclosed. The method for manufacturing the oriented electrical steel sheet according to an embodiment of the present invention comprises the steps of reheating a slab containing 2.0-4.0 wt% of Si, 0.01-0.04 wt% of acid-soluble AL, 0.005 wt% or less of Mn, 0.005 wt% or less of N, 0.005 wt% or less of S, 0.005-0.015 wt% of C, and remainder consisting of Fe and impurities; hot-rolling the reheated slab; cold-rolling a hot-rolled sheet manufactured by hot-rolling without annealing the hot-rolled sheet or cold-rolling after annealing the hot-rolled plate; recrystallization-annealing a cold-rolled sheet and performing nitride annealing; coating boron (B) on the surface of recrystallization-annealed and nitride annealed steel; and performing high-temperature annealing for the recrystallization-annealed and nitride annealed steel.</p> |
