Electrical steel sheet provided with insulating coating

Abstract

There is provided an electrical steel sheet provided with an insulating coating which has high corrosion resistance and high adhesion. The electrical steel sheet provided with an insulating coating includes an electrical steel sheet and an insulating coating disposed on the electrical steel sheet. The insulating coating includes Zr and Fe. The content of Zr in the insulating coating is in the range of 0.05 to 1.50 g/m2 in terms of ZrO2. The compositional ratio between Zr and Fe is such that the molar ratio of Fe to Zr, that is, the ratio of the amount (moles) of Fe included in the insulating coating to the amount (moles) of Zr included in the insulating coating, is in the range of 0.10 to 2.00.
