Title:
ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2019/225523
Kind Code:
A1
Abstract:
This electrolytic capacitor comprises: an anode body having a dielectric layer formed on the surface thereof; a solid electrolyte layer which is in contact with the dielectric layer and which contains a conductive polymer; and an electrolytic solution, wherein the electrolytic solution contains an amidine compound as a first basic component, a composite compound of an inorganic acid and an organic acid as a first acidic component, and, as a second acidic component, at least one selected from boric acid, phosphoric acid , phosphorous acid, hypophosphorous acid, and phosphonic acid, whereby degradation of the electrolytic solution is inhibited, resulting in an increase in the reliability of the electrolytic capacitor.
