Disclosed is a titanium fuel cell separator having excellent conductivity and durability. In the disclosed titanium fuel cell separator (10), a carbon layer (2) is formed on the surface of a substrate (1) formed from pure titanium or a titanium alloy. An intermediate layer (3) is formed on the interface between the substrate (1) and the carbon layer (2). The intermediary layer (3) has lined-up granular titanium-carbide in the direction parallel to the carbon layer (2).
