A non-oriented magnetic steel sheet contains, by mass%, C: 0.005% or less; Si: 2% to 4%; Mn and V: totally 11% or less; and Al: 3% or less, with the balance being Fe and inevitable impurities, wherein a Mn concentration (mass%) and a V concentration (mass%) in a thickness direction satisfy the following formula. 0.1 < Xs Mn , V - Xc Mn , V / t Mn , V < 100 ,
where Xs Mn,V : a sum of the Mn concentrations (mass%) and the V concentration (mass%) at a surface of the steel sheet, Xc Mn,V : a sum of the Mn concentration (mass%) and the V concentration (mass%) at a center of the steel sheet, and t Mn,V : a depth (mm), from the surface of the steel sheet, of a position where the sum of the Mn concentration (mass%) and the V concentration (mass%) is equal to Xc Mn,V . |
