Abstract: An electrical steel sheet with an insulating film having excellent chromium elution resistance, even in the case where the insulating film is baked by utilizing rapid heating, which improves productivity, and a method for manufacturing the steel sheet. The insulating film contains Fe, Cr, an organic resin, and an organic reducing agent on at least one surface of an electrical steel sheet. A ratio of the Fe content to the Cr content (Fe/Cr) is 0.010 to 0.6 in terms of molar ratio in the insulating film.
