According to the invention, in a separator molded member ( 4 A) for a fuel cell which is produced by: loading a complex compound that is configured by bonding graphite powder by means of a thermosetting resin, into a mold ( 14 ); and forming ribs ( 11 ) for forming gas passages by the resin molding process, the surfaces of the ribs ( 11 ) are alkali-treated by, for example, etching by using an alkaline solution, and graphite particles ( 14 ) which are flat and soft are exposed from the top surfaces of the ribs ( 11 ) which function as a contact surface with an electrode in the separator molded member ( 4 A), and resin defective portions ( 15 ) are formed between adjacent graphite particles ( 14 ), whereby the contact area with an electrode is enlarged, so that the performance and efficiency of the fuel cell can be improved by remarkable lowering of the contact resistance.
