Claim 8:
9. A method of producing a grain-oriented electrical steel sheet, comprising
subjecting a steel slab to hot rolling to obtain a hot-rolled steel sheet,
subjecting the hot-rolled steel sheet to cold rolling either once, or twice or more with intermediate annealing performed therebetween to obtain a cold-rolled steel sheet with a final sheet thickness,
then subjecting the cold-rolled steel sheet to primary recrystallization annealing to obtain a primary recrystallized sheet, and
then an annealing separator is applied to a surface of the primary recrystallized sheet, and then the primary recrystallized sheet is subjected to secondary recrystallization annealing to obtain a secondary recrystallized sheet, wherein
the annealing separator is the annealing separator according to claim 1.
