Provided is a stainless steel sheet for a fuel cell separator that combines both excellent press formability and resistance to Fe ion elution. The stainless steel sheet has a chemical composition containing, in mass %, Cr: 18.0% to 24.0% and Ni: 3.00% or less. The steel microstructure includes an austenite phase and a ferrite phase, where the fraction of the austenite phase is 30% or more and the total fraction of the austenite phase and the ferrite phase is 95% or more. Total elongation of the stainless steel sheet is 40% or more.
