Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a solid electrolytic capacitor having excellent heat resistance without transition metal salt as a dopant and oxidant. SOLUTION: In a method of manufacturing the solid electrolytic capacitor including a solid electrolyte made of a conductive polymer, the conductive polymer is formed by performing an oxidative polymerization reaction by bringing a monomer and a dopant into contact with each other. The dopant contains an imidazolium salt of sulfonic acid. By using this dopant, a solid electrolytic capacitor having excellent property is manufactured even if ammonium salt is used as an oxidant.
