The non-oriented electrical steel sheet and its production method having a low iron loss and high magnetic permeability is provided. The cast slab of an electrical steel sheet comprises the following components: Si: 0.1 ~ 2.0wt%; Al: 0.1 ~ 1.0wt%; Mn: 0.10 ~ 1.0wt%; C: ≤0.005wt%; P: ≤0.2wt%; S: ≤0.005wt%; N: ≤0.005wt%; The residual amount of Fe and other inevitable impurities. Permeability of electrical steel sheet satisfies the following
equation: μ 10 + μ 13 + μ 15 ≥13982-586.5P 15/50; μ 10 + μ 13 + μ 15 ≥10000, here, P
15/50 is 50Hz, 1.5T a denotes a core loss under a magnetic induction, μ
10, μ
13 μ
15, and represents the relative permeability of the magnetic induction of 50Hz, 1.0T, 1.3T and 1.5T, respectively. Steel plates may be used to produce highly efficient and ultra-high-efficiency electric motor.
