A stacked solid electrolytic capacitor has an anode foil composed of a valve metal, a cathode foil having carbon grains that are evaporated or physically adhered to a surface thereof, a separator and a solid electrolytic layer composed of a conducting polymer. The anode foil, the separator and the cathode foil are stacked in order. The solid electrolytic layer is formed between the anode foil and the cathode foil.
