Claim 0:
1. A non-oriented electrical steel sheet comprising, as a chemical composition, by mass %:
C: 0.0100% or less;
Si: 1.5% to 4.0%;
sol. Al: 0.0001% to 1.000%;
S: 0.0100% or less;
N: 0.0100% or less;
Ti: 0.0005% to 0.0050%;
one or more selected from the group consisting of Mn, Ni, and Cu: 2.5% to 5.0% in total;
Co: 0.0% to 1.0%;
Sn: 0.00% to 0.40%;
Sb: 0.00% to 0.40%;
P: 0.000% to 0.400%;
one or more selected from the group consisting of Mg, Ca, Sr, Ba, Ce, La, Nd, Pr, Zn, and Cd: 0.000% to 0.010% in total, in which Expression (1) is satisfied in a case where a Mn content (mass %) is indicated as [Mn], a Ni content (mass %) is indicated as [Ni], a Cu content (mass %) is indicated as [Cu], a Si content (mass %) is indicated as [Si], a sol. Al content (mass %) is indicated as [sol. Al], and a P content (mass %) is indicated as [P]; and
a remainder consisting of Fe and impurities,
wherein, in a case where an area ratio of grains having a crystal orientation of an {hkl}<uvw> orientation (within a tolerance of 10°) when measured by EBSD is denoted as Ahkl-uvw, A411-011 is 15.0% or more, and
the non-oriented electrical steel sheet has an average grain size of 10.0 μm to 40.0 μm,

(2×[Mn]+2.5×[Ni]+[Cu])−([Si]+2×[sol. Al]+4×[P])≥1.50%  (1).
