Abstract

A method of manufacturing a fuel cell separator (1) includes: a step of providing resin (19, 21) on surfaces of first carbon particles (17); a step of mixing the first carbon particles (17) provided with the resin (19, 21) and second carbon particles (15) having larger particle diameter than that of the first carbon particles (17) so as to cause the first carbon particles (17) to penetrate gaps between the second carbon particles (15); and a step of performing compression-molding of a mixture of the first carbon particles (17) provided with the resin (19, 21) and the second carbon particles (15) to melt the resin (19, 21) and adhere the first carbon particles (17) to the second carbon particles (15) together with the resin (19, 21). By this method, portions where the carbon particles (15, 17) are in contact with each other are reduced, and the electric resistance is reduced, thus increasing the conductivity.
