Abstract: A non-oriented magnetic steel sheet having excellent bending workability and magnetic characteristics is obtained by continuous annealing. The non-oriented magnetic steel sheet is obtained by the method comprising cold rolling a hot-rolled steel sheet, continuously annealing the steel sheet, and then performing skin pass rolling; the steel has a composition comprising about 0.005 mass % or less of C, about 0.05 to 0.30 mass % of Si, about 0.10 to 0.50 mass % of Mn, about 0.15 to 0.50 mass % of Al, and about 0.0050 mass % or less of N.
