Abstract
There is provided a non-oriented electrical steel sheet in which, in a cross section of a base material in a sheet thickness direction, the number density Nof precipitates with an equivalent circle diameter of 50 to 500 nm present in a range of 2.0 to 5.0 μm from the surface of the base material in the sheet thickness direction is 0.30 pieces/μmor less, and the relationship between the number density Nand the number density Nof precipitates with an equivalent circle diameter of 50 to 500 nm present in a range from the surface of the base material to 2.0 μm satisfies Formula (1):()/()≤0.5 Formula (1).
