PROBLEM TO BE SOLVED: To provide a method for producing a Ti-contg. ferritic stainless steel sheet in which the behavoir of recrystallized grains in hot rolling is controlled and excellent in ridging resistance. SOLUTION: A slab contg., by weight, <=0.010% C, <=0.010% N also so as to satisfy <=0.015% C+N, 6 to 35% Cr, Ti: 6×(C+N)% to 0.5%, and the balance Fe with inevitable impurities is heated to <=1160 deg.C, is subjected to rough rolling in which the cumulative draft is controlled to >=85%, and the final pass finishing temp. is controlled to >=950 deg.C, is next subjected to finish rolling in which the cumulative draft is controlled to >=90%, and the final pass finishing temp. is controlled to >=900 deg.C and is thereafter subjected to pickling, cold rolling and annealing.
