摘要：
In a solid electrolytic capacitor whose cathode is formed by forming an oxide film 2 on an anode-body valve-action metal 1, and forming a conductive polymer layer 3, a graphite layer 4, and a silver layer 5 in succession on the oxide film, the conductive polymer layer 3 contains a sulfonic acid ester compound. In this way, a solid electrolytic capacitor having a low ESR and an excellent moisture resistance and its manufacturing method can be provided.
