To provide an electrode with high cell output and high durability by carrying a catalyst on one surface of an electrode substrate sheet prepared by impregnating carbon particles into a tetrafluoroethylene sheet having air permeability.

Because a polytetrafluoroethylene sheet with high water repellency is used, sufficient water treatment can be applied to an electrode, and an electrode for a fuel cell with high cell output and high durability can be manufactured. Since pores necessary for gas permeability can be ensured between tetrafluoroethylene fibers, cell output can be increased. Appropriate cracks are produced in carbon particles in a gap between tetrafluoroethylene lattices, pores necessary for gas permeability are ensured, and cell output can be increased. An electrode for a fuel cell and a fuel cell with high output and high durability can be manufactured. Preferably, an electrode unit having structure interposing an electrolyte between the electrodes and a conductive separator are stacked to manufacture a fuel cell.
