Zusammenfassung:	This non-oriented electrical steel sheet has a predetermined chemical composition, when EBSD observation is performed on a surface parallel to a steel sheet surface, in a case where a total area is indicated by Stot, an area of {100} orientated grains is indicated by S100, an area of orientated grains in which a Taylor factor M becomes more than 2.8 is indicated by Styl, a total area of orientated grains in which the Taylor factor M becomes 2.8 or less is indicated by Stra, an average KAM value of the {100} orientated grains is indicated by K100, and an average KAM value of the orientated grains in which the Taylor factor M becomes more than 2.8 is indicated by Ktyl, 0.20≤Styl/Stot≤0.85, 0.05≤S100/Stot≤0.80, S100/Stot≥0.5, and K100/Ktyl≤0.990 are satisfied.
