<P>PROBLEM TO BE SOLVED: To solve such a problem of an aluminum electrolytic capacitor using an aluminum foil in the electrode and an extraction lead tab for connecting the electrode and an external terminal that since the extraction lead tab is located in a space between a capacitor element and a lid, it is exposed to halogen such as chlorine flowing out from decomposed electrolyte or a capacitor member after long time use thus causing corrosion disconnection, and to obtain a long life capacitor for high temperature having high breakdown voltage by preventing corrosion of the extraction lead tab surface. <P>SOLUTION: To provide an aluminum electrolytic capacitor in which a higher fatty acid or higher fatty acid aluminum is provided on the extraction lead tab surface on the anode side. <P>COPYRIGHT: (C)2013,JPO&INPIT |
