Grain-oriented electrical steel sheet and method for manufacturing the same

Abstract

An object of the present invention is to provide a grain-oriented electrical steel sheet having improved magnetic properties by overcoming the limitations in improving magnetic properties. [Solution] The present invention relates to a grain-oriented electrical steel sheet and a manufacturing method thereof. The grain-oriented electrical steel sheet of the present invention contains, by weight, 2.0 to 6.0 wt% Si, 0.005 to 0.04 wt%, Mn: 0.01 to 0.2 wt%, N: 0.01 wt% or less, P: 0.0005 to 0.045 wt%, S: 0.010 wt% or less, Sb: 0.01 to 0.05 wt%, C: 0.005 wt% or less, Sn: 0.03 to 0.08 wt%, Cr: 0.01 to 0.2 wt%, Cu: 0.031 to 0.25 wt%, Mo: 0.01 to 0.05 wt%, with the balance being Fe and other unavoidable impurities, and satisfies the following formula 1. <Expression 1> 0.03<[Sn]<│√[Cu]+[Sb]-0.3 2 │ (In the above formula 1, [Sn], [Cu], and [Sb] respectively represent the weight percentages of Sn, Cu, and Sb, √ represents the square root, and ││ represents the absolute value.)
