Non Oriented Electrical Steel Sheet And Method For Manufacturing Same

Abstract: A non-oriented electrical steel sheet according to an embodiment of the present invention comprises, in weight%, Si: 1.5 to 6.0%, Al: 0.1 to 2.0%, Mn: 2.0% or less (exclusive of 0%), and Cu: 0.002 to 0.100%, with the remainder being Fe and inevitable impurities. When measuring Al5?, which is the Al content in the thickness direction from the surface of the steel sheet to 5 µm inward, the ratio of the maximum aluminum content AlMAX to the Al content in the thickness direction from the surface of the steel sheet to 5 µm inward (AlMAX/Al5?) is 5.0 or less, and the number of Al aggregates having a particle diameter of 500 nm or more in a region from the surface of the steel sheet to 5 µm inward is 5 or less per 100 µm length of the steel sheet.
