The purpose of the present invention is to provide a ferritic stainless steel sheet which can exhibit a high scale-removing property even at a high temperature around 1000°C. A ferritic stainless steel sheet characterized by containing 0.001 to 0.020% of C, 0.001 to 0.020% of N, 0.10 to 0.40% of Si, 0.20 to 1.00% of Mn, 16.0 to 20.0% of Cr, 0.30 to 0.80% Nb, 1.80 to 2.40% of Mo, 0.05 to 1.40% of W, 1.00 to 2.50% of Cu and 0.0003 to 0.0030% of B, wherein the above-mentioned components fulfill formula (1) shown below, Fe and unavoidable impurities make up the remainder, and the ferritic stainless steel sheet has an excellent ability of forming an Mn-containing oxide film and an excellent scale-removing property. In the ferritic stainless steel sheet, at least one element selected from N, Al, V, Mg, Sn, Co, Zr, Hf and Ta may be added at a content falling within a specified range. 3 <= (5×Mo)/(3×Mn) <= 20 ...
