PROBLEM TO BE SOLVED: To provide a ferritic stainless steel sheet which is soft, and has excellent workability at an ordinary temperature, and also has high temperature strength and high temperature oxidation resistance more excellent than those of the conventional one. SOLUTION: The steel sheet has a composition containing <=0.02% C, 0.1 to 0.5% Si, <=1.5% Mn, <=0.04% P, <=0.01% S, 10 to 16% Cr, <=1% Ni, 1 to 2% Mo, <=1% Al, 0.2 to 0.8% Nb and <=0.02% N, and containing Si and Mo so as to satisfy Mo×Si<=0.6, and the balance Fe with inevitable impurities, and the surface roughness of the steel sheet is controlled to 0.1 to 2.0μm by Ra. The steel sheet can contain one or more selected from <=0.5% Ti, <=0.5% Zr and <=0.5% V, and one or more selected from <=0.003% B, <=1.0% Cu and <=1.0% W.
