Summary:PURPOSE: To provide a high-performance solid electrolytic capacitor, whose polymerization layer formed at secondary electrolytic polymerization has a shape satisfactory for reducing the dimensions of the capacitor, while the capacitance of the capacitor is not reduced. CONSTITUTION: In the manufacturing process of a solid electrolytic capacitor, whose conductive polymer layer is partially formed by electrolytic polymerization, at least one type of carrier electrolyte with surface active action and at least one type of carrier electrolyte without surface active action are added to solution to be subjected to electrolytic polymerization within respective prescribed concentration ranges. With this constitution, a polymer layer formed at secondary electrolytic polymerization has a satisfactory shape, while reduction in the capacitance of the capacitor is suppressed. 고체 전해 커패시터는 애노드와, 캐소드, 및 유전체를 가지며, 상기 캐소드가 상기 유전체의 표면에 먼저 형성된 1차 화학 중합층과, 그 후, 소정의 용액 안에서 전해 중합을 행함으로써 상기 1차 화학 중합층의 표면에 형성된 2차 전해 중합층으로 이루어진다. 이 고체 전해 커패시터는 상기 소정 용액의 용매에 대하여 계면 활성 작용을 하는 지지 전해질과, 상기 소정 용액의 용매에 대하여 계면 활성 작용을 하지 않는 지지 전해질을 상기 소정 용액에 첨가함으로써 얻어지는 용액에서 전해 중합을 수행함으로써 형성된 2차 전해 중합층을 포함한다.
