<p>The present invention relates to an oriented electrical steel sheet and a manufacturing method thereof. The oriented electrical steel sheet comprises 2.5-4.5 wt% of Si, 0.015-0.040 wt% of Al, 0.01-0.20 wt% of Mn, 0.03-0.09 wt% of C, 0.0010-0.006 wt% of N, 0.0010-0.006 wt% of S, 0.03-0.07 wt% of Sn, 0.01-0.05 wt% of Sb, 0.01-0.05 wt% of P, the remainder being Fe and inevitable impurities. The P and the Sb satisfies P+0.5Sb: 0.0370~0.0630 wt%. The remainder is composed of Fe and the inevitable impurities. A Si content and a C content satisfy Inequality (1). Inequality (1) Si(%)×0.0218 <= C(%) + 0.0194<=Si(%)×0.0234.</p> |
