This non-oriented electromagnetic steel sheet contains, in mass%, from 0.0001% to 0.0040% (inclusive) of C, more than 3.0% but 3.7% or less of Si, from 0.3% to 1.0% (inclusive) of sol. Al, from 0.5% to 1.5% (inclusive) of Mn, from 0.005% to 0.1% (inclusive) of Sn, from 0.0001% to 0.0030% (inclusive) of Ti, from 0.0001% to 0.0020% (inclusive) of S, from 0.0001% to 0.003% (inclusive) of N, from 0.001% to 0.2% (inclusive) of Ni, and from 0.005% to 0.05% (inclusive) of P, with the balance made up only of Fe and impurities. This non-oriented electromagnetic steel sheet has a resistivity rho >= 60 muOmegacm and a saturation magnetic flux density Bs >= 1.945T at room temperature, and satisfies 3.5 <= Si + (2/3) × sol. Al + (1/5) × Mn <= 4.25 with respect to the above-mentioned components. |
