Abstract
A fuel cell separator () which comprises a base () constituted of titanium or a titanium alloy and a conductive carbon layer () that was formed by press-bonding a carbon powder to the base () and that covers the surface thereof; an interlayer () having been formed between the base () and the carbon layer (). The interlayer () has been formed by a heat treatment in an atmosphere containing a slight amount of oxygen, contains titanium carbide yielded by the reaction of the Ti of the base () with the C of the carbon layer (), and has an oxygen content of 0.1-40 at %.
