摘要（英）：

A non-directional electrical steel sheet according to an embodiment of the present invention comprises, in wt%, 2.5 to 3.3% of Si, 0.05 to 1% of Al, 0.05 to 1% of Mn, 0.01% or less of S (not including 0%), 0.005% or less of N (not including 0%), 0.005% or less of C (not including 0%), 0.005% or less of Ti (not including 0%), 0.005% or less of Nb (not including 0%), 0.001 to 0.1% of P, 0.001 to 0.1% of Sn, and 0.001 to 0.1% of Sb, with the remainder being Fe and unavoidable impurities, and satisfies Formulas 1 to 3 below. [Formula 1] 1.7 ≤ [Si]/([Al] + [Mn]) ≤ 2.9 [Formula 2] 50 ≤ 13.25+11.3*([Si]+[Al]+[Mn]/2) ≤ 60 [Formula 3] 0.025 ≤ [P]+[Sn]+[Sb] ≤ 0.15 (In Formulas 1 to 3, [Si], [Al], [Mn], [P], [Sn], and [Sb] represent the content (in wt%) of Si, Al, Mn, P, Sn, and Sb, respectively.)
