이 방향성 전자 강판은, 모재 강판과, 모재 강판 위에 접하여 배치된 중간층과, 중간층 위에 접하여 배치되어 최표면이 되는 절연 피막을 갖고, 절단 방향이 판 두께 방향과 평행이 되는 절단면에서 보았을 때, 상기의 절연 피막이, 중간층 위에 접하는 영역에, 결정성 인화물을 함유하는 결정성 인화물 함유층을 갖는다. A grain-oriented electrical steel sheet includes: a base steel sheet; an intermediate layer arranged in contact with the base steel sheet; and an insulation coating arranged in contact with the intermediate layer to be an outermost surface, in which the insulation coating has a crystalline phosphide-containing layer containing a crystalline phosphide in an area in contact with the intermediate layer when viewing a cross section whose cutting direction is parallel to a thickness direction.
