Title:

ELECTROLYTIC CAPACITOR

Document Type and Number:

WIPO Patent Application WO/2020/021679

Kind Code:

A1

Abstract:

This electrolytic capacitor 1 stores, in a main body case 3, a capacitor element 10 that holds an electrolytic solution by winding a first electrode body 11 and a second electrode body 12 with a separator 13 therebetween, wherein: the electrolytic capacitor 1 has a conductive polymer particle band 23 which is provided between the first electrode body 11 and the second electrode body 12 and in which particles of a conductive polymer 22 are densely arranged along the long-side direction of the separator 13; a cellulose derivative 21 is contained in the conductive polymer particle band 23; and the conductive polymer particle band 23 occupies, in the short-side direction Y, half or more of the separator 13 in at least one region with respect to the center line C in the short-side direction of the separator 13.
