PROBLEM TO BE SOLVED: To provide a separator for a fuel cell having excellent electric conductivity, corrosion resistance, high productivity, and inexpensive manufacturing cost. SOLUTION: A separator 2 for a fuel cell forming a gas flow pass 7 in cooperation with a flat plate electrode 6 of a cell 1 consists of a low electric resistance metal plate 9 and an amorphous carbon film 10 constituting a gas flow forming surface (a) by covering the metal plate 9. A hydrogen content CH of the amorphous carbon film 10 is set for 1 atom %<=CH<=20, in order to enhance electric conductivity of the film 10. |
