The electromagnetic steel sheet (1) includes a base material (2) of an electromagnetic steel and an insulating coating (3) formed on the surface of the base material (2). (1.8? 3 [Fe] / [P] +?? M [M] / [P]? 3.6, 0.6?? M M [M] in an area of 50% or more area of a cross section parallel to the thickness direction of the insulating film 3 M] / [P]? 2.4 and 0.6? 3 [Fe] / [P]? 2.4. [Fe] is the ratio (atom%) of Fe, [P] is the ratio (at%) of P, and [M] are Al, Zn, Mg and the ratio (at%) of each of Ca, n M is Al, Zn, Mg and Ca, respectively. |
