PROBLEM TO BE SOLVED: To provide a manufacturing method in which, while high tensile stress is applied on a steel sheet without deterioration the adhesive properties of a tension film, and high insulating properties can be maintained and to provide a grain oriented silicon steel sheet obtained in the same manufacturing method. SOLUTION: In this method, a grain oriented silicon steel sheet extremely low in core loss, is produced, in which the formation of forsterite is suppressed, or forsterite is removed. An organometallic compound having a hydrophilic group or an organic coupling group and further having a metallic coupling group is mixed with a water slurry or an aqueous for a substance to form the tensile film after baking solution of the raw material, this mixture is applied on a steel sheet, bucked and annealed to form the tension film. |
