摘要： A grain-oriented electrical steel sheet has a tension film that does not include chromium. In the present invention, the tension film, including a phosphate and silica as constituents, includes a manganese compound and a potassium compound. The mole ratio K/Mn of potassium to manganese in the film is set to a certain range. The film can be produced by preparing a coating solution by adding a compound, which includes the phosphate and the silica and also includes the potassium and the manganese, and applying the coating solution on a grain-oriented electrical steel sheet after final annealing is completed, followed by drying and baking.
