PROBLEM TO BE SOLVED: To provide a solid electrolytic capacitor capable of exhibiting a high DCL attenuation rate even under dry conditions. SOLUTION: In a solid electrolyte, poly (4- (2,3-dihydrothieno- [3,4-b] [1,4] dioxin-2-ylmethoxy) -1-butane-sulfonic acid, salt) and / or An intrinsically conductive polymer containing poly (4- (2,3-dihydrothieno- [3,4-b] [l, 4] dioxin-2-ylmethoxy) -l-propanesulfonic acid, salt) is used.
