A non-oriented electrical steel sheet has a chemical composition comprising C: not more than 0.005 mass%, Si: 1.5-4 mass%, Mn: 1-5 mass%, P: not more than 0.1 mass%, S: not more than 0.005 mass%, Al: not more than 3 mass%, N: not more than 0.005 mass%, Pb: not more than 0.001 mass% and the remainder being Fe and inevitable impurities or a chemical composition comprising C: not more than 0.005 mass%, Si: 1.5-4 mass%, Mn: 1-5 mass%, P: not more than 0.1 mass%, S: not more than 0.005 mass%, Al: not more than 3 mass%, N: not more than 0.005 mass%, Pb: not more than 0.0020 mass% and further one or two of Ca: 0.0005-0.007 mass% and Mg: 0.0002-0.005 mass%, and has a stable and excellent high-frequency iron loss property even when Mn content is high. |
