摘要： A method of manufacturing an electrolytic capacitor includes preparing a dielectric film formed on a surface of an anode foil, forming a first conductive polymer layer on a surface of the dielectric film by immersing the anode foil in first dispersion solution including conductive polymer particles and forming a second conductive polymer layer covering the first conductive polymer layer solvent by immersing the anode foil in second dispersion solution including second conductive polymer particles and second solvent. The surface of the anode foil has plural pits formed therein. The second dispersion solution has a pH value farther from 7 than the first dispersion solution does. This configuration can suppress damages to the dielectric film.

摘要： A metalized film capacitor includes metalized films, each of which is formed of an insulating film made of dielectric, and a vapor deposited metal electrode formed on an upper surface of the insulating film. An end of the vapor deposited metal electrode extends together with an end of the insulating film, and both the ends are connected to an electrode terminal. The vapor deposited metal electrode of the metalized film includes a center region and a low resistance section that is made of Al—Zn—Mg alloy. The low resistance section is disposed at an end of the electrode and is thicker than the center region. This metalized film capacitor has high humidity resistance.
