Abstract:
A non-oriented electrical steel sheet has a chemical composition in which α-γ transformation can occur and which contains at least, in terms of mass %, at most 0.010% of C, 1.50% to 4.00% of Si, 0.0001% to 1.0% of sol. Al, at most 0.010% of S, at most 0.010% of N, and a total of 2.50% to 5.00% of at least one selected from the group consisting of Mn, Ni, and Cu, with the balance including Fe and impurities, wherein when an average grain size of {411} crystal grains is defined as d411 and an average grain size of {111} crystal grains is defined as d111, d411/d111≥1.10.
