摘要： In a solid electrolyte capacitor including a solid electrolyte implemented by a conducting polymer produced by the chemical oxidative polymerization of a polymerization system containing a monomer, a cation serving as an oxidizer, and an anion serving as a dopant, the polymerization system contains the anion in a stoichiometrically excessive amount relative to the cation. The conductivity of a conducting polymer included in the capacitor is prevented from being deteriorated in a high temperature atmosphere, so that a desirable ESR is preserved during 125° C. heat test. In addition, a conductive high polymer layer having an extremely desirable film property is formed. This successfully prevents stresses ascribable to the expansion and contraction of a seal resin from being transferred to the capacitor during heat test, and thereby protects LC and ESR from deterioration.

摘要： A solid electrolytic capacitor using a conductive polymeric compound as a solid electrolyte is disclosed, wherein a powder is dispersed in the conductive polymer to provide unevenness on the surface of the solid electrolyte, thereby increasing the surface area, whereby a mechanical adhesion between the solid electrolyte and a cathode conductor layer is increased. The conductive polymer comprises a first conductive polymer layer which contacts a dielectric layer at an anode body side, and a second conductive polymer layer which contacts the cathode conductor layer side, and the powder is dispersed in the second conductive polymer layer. By this constitution, tan .delta. and an equivalent series resistance (ESR) of the solid electrolytic capacitor are decreased.
