Abstract
Provided is a grain-oriented electrical steel sheet having excellent magnetic properties. In an aging treatment method of subjecting a steel sheet before final cold rolling to aging treatment in a process of producing a grain-oriented electrical steel sheet, a total aging amount of carbon during a period from completion of cooling in annealing before the final cold rolling to biting in the final cold rolling is 0.02 μm to 0.5 μm in terms of diffusion distance of carbon.
