The purpose of the present invention is to provide: a solid electrolytic capacitor including both a solid electrolyte and an electrolyte solution between electrode foils, wherein a rise in ESR can be sufficiently suppressed for a long time and for which a long life can be realized; and a method for manufacturing the same. To achieve the foregoing, this solid electrolytic capacitor (1) includes an amine represented by general formula (1) as the base component of an electrolyte solution 2g). In the formula, R1 represents hydrogen, an alkyl group, a hydroxyalkyl group, or an alkoxyalkyl group.　R2, R3, R4, and R5 each independently represent hydrogen, an alkyl group, a hydroxy group, a hydroxyalkyl group, an alkoxy group, or an alkoxyalkyl group.　The ends of R2 and R3 may join to form a ring.　The ends of R4 and R5 may join to form a ring.
