The resultant steel plate is cold rolled once or is cold rolled two or more times while process annealed between cold rolling stages. The resultant steel sheet is subjected to decarburizing annealing at 780 to 880 deg.C soaking temperature. After a separation agent at annealing is applied to the surface of the steel sheet, secondary recrystallization annealing and purification annealing are performed. The process of manufacturing the grain oriented silicon steel sheet consists of a series of stages mentioned above.  At this time, decarburizing annealing is carried out at (12 to 40) deg.C/s average temperature rise rate through the temperature region from the ordinary temperature to 750 deg.C and at (0.5 to 10) deg.C/s average temperature rise rate through the temperature region from 750 deg.C to soaking temperature.
