摘要：
In a non-oriented electrical steel sheet, Si: not less than 1.0 mass% nor more than 3.5 mass%, Al: not less than 0.1 mass% nor more than 3.0 mass%, Ti: not less than 0.001 mass% nor more than 0.01 mass%, Bi: not less than 0.001 mass% nor more than 0.01 mass%, and so on are contained. (1) expression described below is satisfied when a Ti content (mass%) is represented as [Ti] and a Bi content (mass%) is represented as [Bi]. Ti ≦ 0.8 × Bi + 0.002
