Provided is a ferritic stainless steel sheet for current collectors for sulfide-based solid-state batteries, which has excellent sulfidation resistance and adhesiveness. The ferritic stainless steel sheet has a component composition containing Cr in an amount of 16% by mass or more, wherein the surface of the ferritic stainless steel sheet has an uneven structure having recessed portions and projecting portions, the average height of the projecting portions is 20 to 50 nm inclusive, the average distance between the projecting portions is 20 to 200 nm inclusive, and the [Cr]/[Fe], i.e., the ratio of the atom concentration of Cr that is present in a form other than the metal form to the atom concentration of Fe that is present in a form other than the metal form, on the surface of the ferritic stainless steel sheet is 1.0 or more. |
