Provided is a ferritic stainless steel sheet for SOFC separator use not impaired in electrical conductivity and adhesion of the oxide film and excellent in durability without relying on the addition of rare earth elements. A ferritic stainless steel sheet excellent in electrical conductivity and adhesion of an oxide film comprised of steel containing, by mass%, C : 0.02% or less, Si : 0.15% or less, Mn : 0.3 to 1%, P : 0.04% or less, S : 0.003% or less, Cr : 20 to 25%, Mo : 0.5 to 2%, Al : 0.1% or less, N : 0.02% or less, and Ti : 0.001 to 0.5%, having a balance of Fe and unavoidable impurities, and satisfying the formula (1) 2.5 < Mn / Si + Al < 8.0 wherein [Mn], [Si], and [Al] mean contents (mass%) of the elements, respectively.
