Beschreibung
Zusammenfassung:	This non-grain-oriented electrical steel sheet is a non-grain-oriented electrical steel sheet including a silicon steel sheet as a base material, wherein the silicon steel sheet has a predetermined mechanical property depending on a direction with respect to a rolling direction, and the difference between a maximum value and a minimum value of diameters of circular holes after punching with a substantially circular die is 0.20% or less of the average value of the maximum value and the minimum value.
