Claim 0:
1. A hybrid electrolytic capacitor comprising:
a cathode comprising a cathode substrate composed of a valve metal, an oxide layer composed of an oxide of the valve metal provided on a surface of the cathode substrate, an inorganic conductive layer having an inorganic conductive material provided on a surface of the oxide layer, and an organic conductive layer having a conductive polymer provided on a surface of the inorganic conductive layer;
an anode comprising an anode substrate composed of a valve metal, and a dielectric layer composed of an oxide of the valve metal that composes the anode substrate and provided on a surface of the anode substrate; and
a composite electrolyte layer comprising a solid electrolyte layer having conductive polymer particles that is provided between and in contact with the organic conductive layer of the cathode and the dielectric layer of the anode, and an electrolytic solution filled between the conductive polymer particles in the solid electrolyte layer,
wherein the organic conductive layer in the cathode has a density in the range of 1.15 to 1.80 g/cm3.
