Abstract: A titanium or titanium alloy material for a fuel cell separator has a surface shape in which a plurality of projections are distributed, and a titanium oxide film on a surface of the projections. Fine projections are assumed to increase the contact conductivity remarkably. By increasing contact conductivity with carbon and durability of a titanium or titanium alloy material for a fuel cell separator, the lifetime of a fuel cell may be increased. The material has high usability in the cell manufacturing industry.
