Abstract
A non-oriented electrical steel sheet includes C: 0 to 0.0050 mass %, Si: 0.50 to 2.70 mass %, Mn: 0.10 to 3.00 mass %, Al: 1.00 to 2.70 mass %, and P: 0.050 to 0.100 mass %. In the non-oriented electrical steel sheet, Al/(Si+Al+0.5×Mn) is 0.50 to 0.83, Si+Al/2+Mn/4+5×P is 1.28 to 3.90, Si+Al+0.5×Mn is 4.0 to 7.0, the ratio of the intensity of {100} plane I{100} to the intensity of {111} plane I{111} is 0.50 to 1.40, the specific resistance is 60.0×10Ω·m or higher at room temperature, and the thickness is 0.05 mm to 0.40 mm.
