A method of manufacturing an oriented silicon steel sheet improved in magnetic characteristics, in which a hot-rolled steel sheet of oriented silicon steel containing about 0.01 to 0.10 % by weight of Al and about 0.01 to 0.04 % by weight of Sb as inhibitor components is heat-treated and cold-rolled one time or two or more times to have a final thickness. In the final heat treatment and final cold rolling alone, the steel sheet is quenched from a temperature of about 900 to 1,100°C to a temperature equal to or lower than about 50°C, is heat-treated at about 50 to 150°C for about 30 sec. to 30 min. while applying a tensile stress of about 0.5 to 20 kg/mm2, is thereafter cold-rolled by a reduction rate of about 35 to 70 % in a tandem rolling method, is aged at about 200 to 400°C for about 10 sec. to 10 min., and is finished by cold rolling to have the final thickness.
