Claim 11:
12. A method for manufacturing a hybrid electrolytic capacitor comprising:
a cathode formation process having a step of forming an inorganic conductive layer using an inorganic conductive material on a surface of an oxide layer composed of an oxide of a valve metal formed on a surface of a cathode substrate composed of the valve metal, and a step of forming an organic conductive layer having a conductive polymer on a surface of the inorganic conductive layer via electrolytic polymerization of a monomer having a π-conjugated double bond;
an anode formation process of forming a dielectric layer by oxidizing a surface of an anode substrate composed of a valve metal; and
a complex electrolyte layer formation process having a step of forming a solid electrolyte layer by filling a dispersion liquid with conductive polymer particles and a dispersion medium between the organic conductive layer of the cathode and the dielectric layer of the anode and drying the dispersion liquid, and a step of impregnating the solid electrolyte layer with an electrolytic solution,
wherein the organic conductive layer has a density in the range of 1.15 to 1.80 g/cm3.
