<p>Provided is a method for manufacturing a grain-oriented electrical steel sheet with highly stable magnetic characteristics using a component system containing no inhibitor. In the manufacture of the grain-oriented electrical steel sheet using a slab made of the component system containing no inhibitor, the slab contains a total of 10-150 ppm of at least one kind of microelement selected from B, Nb, and V, the mass ratio of Al and N included as impurities is Al/N = 1.4; and preferably, the average temperature increase rate between 600°C and 800°C during recrystallization annealing is 15°C/s or higher.</p> |
