摘要： Provided is a method of producing an electrolytic capacitor being higher in capacitance, lower in leakage current, and difficult to deteriorate these properties even when processed in a heat-treatment process such as reflow soldering process. In the method of producing a solid electrolytic capacitor, firstly, an anode containing a valve metal is prepared. Then, the anode is anodized in an aqueous solution of 0.1% by weight of ammonium hexafluorosilicate to form a dielectric layer on the surface of the anode. An electrolyte layer of polypyrrole is formed on the dielectric layer, and further a cathode is formed on the electrolyte layer. Subsequently, an anode lead is connected to the anode and a cathode lead is connected to the cathode, and these are covered with a resin layer of an epoxy resin.

摘要： A method includes the following steps: forming a porous anode body using powder of valve metal or an alloy thereof; forming a dielectric layer on the surface of the anode body; soaking the anode body having the dielectric layer in a liquid containing a conductive-polymer monomer, thereby making the monomer adhere to the dielectric layer of the anode body; forming a first conductive polymer layer by soaking the anode body having the monomer adhered thereto in an oxidizing agent solution, thereby polymerizing the monomer by liquid-phase chemical polymerization; forming a second conductive polymer layer by bringing the conductive-polymer monomer into contact with the surface of the anode body having the first conductive polymer layer in a gas phase, thereby polymerizing the monomer by gas-phase chemical polymerization; and forming a third conductive polymer layer by soaking the anode body having the second conductive polymer layer in a liquid containing a monomer of a conductive polymer layer, thereby polymerizing the monomer by electrolytic polymerization.
