Packaging for solid electrolytic capacitor and method of manufacturing the solid electrolytic capacitor

摘要

A solid electrolytic capacitor includes a capacitor element having a niobium oxide layer (12) arranged between an anode (11) and a cathode (17), and an outer package (1) covering the capacitor element. The niobium oxide layer contains fluorine and phosphorus, and the outer package contains epoxy resin, phenol resin, filler and an imidazole compound. The resin composition containing epoxy resin, phenol resin, filler and the imidazole compound is cured by heat in the molding process. The stress which occurs when the resin composition is cured in the molding process is suppressed by the composition.
