摘要： A fabrication method of a solid electrolytic capacitor is provided, which decreases the leakage current of a solid electrolytic capacitor without deterioration of ESR. This method is comprised of the steps (a) to (e). In the step (a), a capacitor body is formed by a valve metal, the body serving as an anode of the capacitor. In the step (b), an oxide layer of the valve metal is formed to cover a surface of the capacitor body by anodic oxidation, the oxide layer serving as a dielectric of the capacitor. In the step (c), a layer of an organic conducting polymer is formed on the oxide layer, the layer of the organic conducting polymer serving as a solid electrolyte of the capacitor. In the step (d), the capacitor body with the oxide layer and the layer of the organic conducting polymer is immersed in a reoxidation solution, the reoxidation solution containing a mixture of water and alcohol or a mixture of water and ketone as a solvent. In the step (e), a voltage is applied to the capacitor body to reoxidize the oxide layer in the reoxidation solution by anodic oxidation, thereby healing defects of the oxide layer. The amount of alcohol or ketone is preferably 30 vol % to 50 vol %.

摘要： First, an anode lead is led out of an anode member. Next, a dielectric film is formed at a surface of the anode member by anodic oxidation to form a capacitor element. Thereafter, a water-repellent agent is applied on a predetermined position of the anode lead. In succession, the capacitor element is immersed in an oxidant solution of a mixture solvent of alcohol and water, followed by drying. The capacitor element is then immersed in an alcoholic solution of a conductive polymeric monomer to polymerize a conductive polymer electrolyte on a surface of the capacitor element by chemical oxidation.

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.
