<p>PROBLEM TO BE SOLVED: To provide an oxidant solution for manufacturing a conductive polymer which makes it possible to manufacture a solid electrolytic capacitor superior in high electrostatic capacitance and low ESR, and having heat resistance; a solid electrolytic capacitor produced by use of such an oxidant solution; and a method for manufacturing such a solid electrolytic capacitor.SOLUTION: An oxidant solution comprises an organic ferric sulfonate salt serving as an oxidant. The organic ferric sulfonate salt includes, as an organic sulfonic acid, an alkylbenzene sulfonic acid expressed by the general formula (1), and a benzene sulfonic acid expressed by the general formula (2) in a particular proportion. A solid electrolytic capacitor superior in high electrostatic capacitance and low ESR and having heat resistance comprises a conductive polymer formed by use of the oxidant solution. A method for manufacturing such a solid electrolytic capacitor comprises: using the oxidant solution.</p> |
