A process for producing a lead wire of hard carbon for supplying power to a fuel battery, including the steps of mixing carbon powder and monomer or precondensate of furan resin with binder containing as a main ingredient chlorine-containing vinyl resin which is carbonized after calcining, uniformly mixing and dispersing the mixture composition, applying high shearing force to the mixture composition, extrusion molding the composition in a rod shape, insolubilizing and infusibilizing the molding, and calcining the molding in an inert gas atmosphere, thereby obtaining the lead wire of hard carbon for supplying power to the fuel battery. Thus, the process can industrially simply and inexpensively produce lead wires of hard carbon for supplying power with small electric resistance to the fuel battery which does not consume electricity generated as Joule heat, and has excellent corrosion resistance against electrolytes of high temperature and high acid concentration.
