摘要：
An electrical steel sheet is provided with an insulating coating which has inorganic with some organic materials, the insulating coating including inorganic components and an organic resin, the insulating coating contains, as the inorganic components, a Zr compound, a B compound, and a Si compound, specifically, when expressed as percentages in the dry coating, 20% to 70% by mass of the Zr compound (in terms of ZrO2), 0.1% to 5% by mass of the B compound (in terms of B2O3), and 10% to 50% by mass of the Si compound (in terms of SiO2), and the balance containing the organic resin.
