Abstract

There are provided a grain-oriented electrical steel sheet having excellent magnetic properties and a method for manufacturing the same. More particularly, there are provided a grain-oriented electrical steel sheet whose magnetic properties is remarkably improved to the extent that is unexpected in similar component systems in the prior art by adjusting contents of the components and improving the manufacturing method and, a method for manufacturing the same. The grain-oriented electrical steel sheet essentially comprises 0.Q3 to 0.07% by weight of Sn, 0.01 to 0.5% by weight of Sb, and 0.01 to 0.05% by weight of P.
