In a capacitor 10, a first electrode 21, a dielectric layer 23, a solid
electrolytic layer 50 and a second electrode 31 are provided. In a
manufacturing process, the dielectric layer 23 and a first solid
electrolytic layer 24 formed by a chemical polymerization film are
provided on the first electrode 21 side, while a second solid
electrolytic layer 32 formed by an electrolytic polymerization film is
provided on the second electrode 31 side. Then, the solid electrolytic
layers are bonded to each other.
