PROBLEM TO BE SOLVED: To provide a method of producing a high purity, ferritic and thin stainless steel sheet excellent in ridging-resistance. SOLUTION: A continuously cast slab of a high purity ferritic stainless steel in which the components of the steel are regulated so as to contain, by weight, <=0.015% C, <=0.020% N, <=1% Mn, 10.5 to 12% Cr and 8×(C+N) to 0.4% Ti and furthermore so as to satisfy either <=0.2% Si or <=0.03% Al, and the balance Fe with inevitable impurities is heated at <=1,150 deg.C, is subjected to hot rolling, is subjected to annealing of executing holding in the temp. range of 800 to 900 deg.C for >=2hr according to necessary and is thereafter subjected to cold rolling and annealing.
