PROBLEM TO BE SOLVED: To provide a solid electrolyte having improved conductivity and heat-resistance properties, to provide an electrolytic capacitor that has low ESR and can withstand harsh conditions, and to provide a manufacturing method of the electrolytic capacitor. SOLUTION: The solid electrolyte contains aπconjugated system conductive polymer expressed by an expression (1). In the expression (1), R is one of a hydrogen atom, an alkyl group having 1 to 12 carbons, a phenyl group, a substituted phenyl group, a cycloalkyl group, a naphthalene group, a hydroxy group, an alkoxy group having 1 to 12 carbons, an alkylether group, a carboxyl group, a carboxyester group, a sulfo group, and a halogen group. The capacitor has a negative electrode comprising a solid electrolyte. COPYRIGHT: (C)2007,JPO&INPIT
