A method for manufacturing a grain oriented electrical steel sheet having a forsterite film, the method comprising subjecting a heated slab to hot rolling and then to cold rolling one time or two times with intermediate annealing to attain a final sheet thickness, subjecting the steel sheet to decarburization annealing, thereafter applying an annealing separator to the surface of the steel sheet, subsequently subjecting the steel sheet to final finishing annealing to form a forsterite film, wherein streaky defective parts are formed on the surface of the forsterite film by controlling the cold rolling conditions so that the surface of the steel sheet before decarburization annealing has portions that are convex mainly in the rolling direction, or by applying the annealing separator with a brush so as to leave streaks in which the annealing separator is missing, or by increasing the oxidizing ability P (H 2 O)/P (H 2 ) of the atmosphere during the decarburization annealing so that portions that are not coated with the annealing separator become the streaky defective parts on the resultant forsterite film after final finishing annealing, screening a grain oriented electrical steel sheet based on whether or not the total area percentage of the streaky defective parts scattered on the forsterite film as viewed from above the surface is less than 1.5% by determining the total area percentage of the streaky defective parts using the equipment, methods and procedures described in the description, and a magnetic domain refining step of performing magnetic domain refining treatment on the surface of a grain oriented electrical steel sheet screened as acceptable in the screening step, wherein the grain oriented electrical steel sheet is screened as acceptable in the screening step, when the total area percentage of the streaky defective parts scattered on the forsterite film as viewed from above the surface is less than 1.5%. subjecting a heated slab to hot rolling and then to cold rolling one time or two times with intermediate annealing to attain a final sheet thickness, subjecting the steel sheet to decarburization annealing, thereafter applying an annealing separator to the surface of the steel sheet, subsequently subjecting the steel sheet to final finishing annealing to form a forsterite film, wherein streaky defective parts are formed on the surface of the forsterite film by controlling the cold rolling conditions so that the surface of the steel sheet before decarburization annealing has portions that are convex mainly in the rolling direction, or by applying the annealing separator with a brush so as to leave streaks in which the annealing separator is missing, or by increasing the oxidizing ability P (H 2 O)/P (H 2 ) of the atmosphere during the decarburization annealing so that portions that are not coated with the annealing separator become the streaky defective parts on the resultant forsterite film after final finishing annealing, screening a grain oriented electrical steel sheet based on whether or not the total area percentage of the streaky defective parts scattered on the forsterite film as viewed from above the surface is less than 1.5% by determining the total area percentage of the streaky defective parts using the equipment, methods and procedures described in the description, and a magnetic domain refining step of performing magnetic domain refining treatment on the surface of a grain oriented electrical steel sheet screened as acceptable in the screening step, wherein the grain oriented electrical steel sheet is screened as acceptable in the screening step, when the total area percentage of the streaky defective parts scattered on the forsterite film as viewed from above the surface is less than 1.5%. <EOS>
