Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method of high- reliable electrolytic capacitor superior in moisture resistance.SOLUTION: Disclosed is a manufacturing method of an electrolytic capacitor including a capacitor element which has an anode body, a dielectric layer and a solid electrolyte layer. The manufacturing method of the electrolytic capacitor has a process to form the solid electrolyte layer, which includes: a first step to form a first conductivity polymer layer; a second step to bring a solution containing an aromatic sulfonic acid having a carboxyl group and a solvent to the first conductive polymer layer.SELECTED DRAWING: Figure 2 【課題】耐湿性に優れ信頼性の高い電解コンデンサの製造方法を提供する。【解決手段】本発明は、陽極体と誘電体層と固体電解質層とを有するコンデンサ素子を備えた電解コンデンサの製造方法であって、固体電解質層を形成する工程は、第１の導電性高分子層を形成する第１の工程と、カルボキシル基を有する芳香族スルホン酸と溶媒とを含有する溶液を第１の導電性高分子層に付着させる第２の工程と、を有する、電解コンデンサの製造方法である。【選択図】図２
