An electromagnetic steel sheet with an insulating coating excellent in corrosion resistance and adhesion is provided. Wherein the insulating film contains Zr and Fe, the content of Zr is 0.05 to 1.50 g / m 2 in terms of ZrO 2 , and the content ratio of Zr and Fe is in a molar ratio (Molar amount of Fe in the insulating film / amount of Zr in the insulating film) of 0.10 to 2.00. The insulating film further contains Si, and the content ratio of Zr and Si is preferably 2.00 or less in molar ratio (amount of Si in insulating film / amount of Zr in insulating film). |
