Provided is a fuel cell separator that can maintain a low contact resistance for a long period of time while being used for a fuel cell, by using a carbon film that can be formed with high productivity. The fuel cell separator (10) is provided with: a base material (1) comprising titanium or titanium alloy; and a conductive carbon layer (2) that is formed by compression bonding carbon powder onto the base material (1), and covers the surface thereof. Between the base material (1) and the carbon layer (2), particle-like titanium carbide (31) and carbon-titanium solid solution (32) generated by reacting the titanium of the base material (1) and carbon of the carbon layer (2) with each other through heat treatment are connected, forming an intermediate layer (3). |
