Abstract
When a Si content (mass %) is set to [Si], an Al content (mass %) is set to [Al], and a Mn content (mass %) is set to [Mn], a parameter Q represented by 'Q=[Si]+2[Al]−[Mn]' is 2.00 or more, the total mass of S contained in sulfides or oxysulfides of Mg, Ca, Sr, Ba, Ce, La, Nd, Pr, Zn, or Cd is 40% or more of the total mass of S contained in a non-oriented electrical steel sheet, a {100} crystal orientation intensity is 3.0 or more, a thickness is 0.15 mm to 0.30 mm, and an average crystal grain diameter is 65 μm to 100 μm.
