摘要： In production of an electrode for an aluminum electrolytic capacitor, a hydrated film is formed onto an aluminum electrode including a porous layer by immersing the aluminum electrode into a first hydration treatment liquid having a temperature of 80° C. or more in a first hydration treatment step (ST1) and thereafter the aluminum electrode is heated in an atmosphere having a temperature of 150° C. or more and 350° C. or less in a dehydration step (ST2). Subsequently, a hydrated film is formed onto the aluminum electrode by immersing the aluminum electrode into a second hydration treatment liquid having a temperature of 80° C. or more in a second hydration treatment step (ST3) and thereafter chemical formation of the aluminum electrode is performed at 400 V or more and further 600 V or more in a chemical formation step.

摘要： A method for manufacturing a solid electrolytic capacitor with excellent ESR properties and a solid electrolytic capacitor. A method for manufacturing a solid electrolytic capacitor, wherein an anode body is obtained by forming a dielectric oxide film on the surface of a sintered body that is formed by sintering a molded body formed of a valve acting metal powder or on the surface of a roughened valve acting metal foil, and a solid electrolyte layer is formed on the surface of the anode body. This method for manufacturing a solid electrolytic capacitor is characterized by steps for forming a solid electrolyte layer including a protrusion forming process where protrusions formed of manganese dioxide and having an average diameter of 10˜102 nm are formed on the surface of the dielectric oxide coating film so that the protrusions are scattered about like islands and the surface coverage is 1˜20% and a conductive polymer layer forming process where a conductive polymer layer is formed on the surfaces of the projections and the dielectric oxide coating film.
