Summary: | Disclosed are a non-oriented electrical steel sheet, and a method to manufacture the same. The non-oriented electrical steel sheet of the present invention comprises: less than or equal to 0.005 wt% of C (not including 0 wt%); less than or equal to 2 wt% of Si (not including 0 wt%); less than or equal to 0.08 wt% of Mn; less than or equal to 0.02 wt% of P (not including 0 wt%); 0.001-0.005 wt% of S; less than or equal to 0.005 wt% of Al; less than or equal to 0.005 wt% of N (not including 0 wt%); less than or equal to 0.005 wt% of Ti (not including 0 wt%); 0.05-0.2 wt% of either Sn or Sb; and the rest of Fe and unavoidably added impurities. The Si and the Mn satisfy 0.7 <=([Si]-[Mn])<=1.7, where ([Si], [Mn] respectively mean wt%).
