PROBLEM TO BE SOLVED: To provide a method of manufacturing a high purity stainless steel sheet excellent in ridging resistance. SOLUTION: A high purity ferritic stainless steel, in which steel components are regulated so that the steel contains, by mass, <=0.015% C, <=0.020% N, <=1% Mn, 10.5-12% Cr, and 8×(C+N) to 0.4% Ti and further contains either of <=0.2% Si and <=0.03% Al and has the balance Fe with inevitable impurities, is used. This steel is held, in the course of hot rolling, at 970 to 1070 deg.C for >=5 min.
