    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.
