Abstract Disclosed herein is a method of manufacturing a base steel sheet, which method comprises combined steps of: not rolling a steel slab containing not more than 0.0070% by weight of C (hereinafter referred to breifly as "%"), not more than 0.1% of Si, not more than 0.5% of Mn, 0.010 to 0.080% of Al, not more than 0.0050% of N, not more than 0.030% of S provided that the ratio of Mn/S is not less than 10, and not more than 0.030% of P while the hot rolling being terminated at a finish temperature of not less than 800°C; cold rolling thus obtained hot rolled steel sheet in an ordinary manner; continuously annealing the cold rolled steel sheet in which heating is done up to a temperature from a recrystallization temperature to 800°C, followed by cooling; and then temper rolling the annealing steel sheet at a reduction of not less than 7% by using two or more stand rolling mill, whereby the thus obtained base sheet, to be surface-treated may be utilized for a tinplate or a tin free steel in which no stretcher strain is formed even after baking treatment.
