Disclosed herein is a method for regenerating a separator for a fuel cell in which the separator is composed of a substrate of Ti or Ti alloy and a conductive film formed thereon. The method includes a step of removing the conductive film from the separator for a fuel cell and also removing part of the surface of the substrate, thereby giving a regenerated substrate, and a step of forming a regenerated conductive film on the regenerated substrate. The conductive film and the regenerated conductive film are at least one species of noble metal or alloy thereof selected from the group of noble metals consisting of Au, Pt, and Pd, or an alloy composed of at least one species selected from the group of noble metals and one species selected from the group of metals consisting of Ti, Zr, Hf, Nb, Ta, and Si.
