Zusammenfassung:To provide a solid electrolytic capacitor that can suppress ESR increases and achieve high reliability.SOLUTION: A solid electrolytic capacitor includes: a sheet laminate formed by alternately laminating a plurality of flat film capacitor elements in which a dielectric layer and a solid electrolyte layer are successively formed on the surface of a flat film anode electrode foil, and a plurality of flat film cathode electrode foils; and an insulating resin that seals the sheet laminate. In plan view, a ring-shaped insulating dam is provided between each capacitor element and the cathode electrode foil, and a first adhesive and a second adhesive having conductivity are placed in the area surrounded by the dam.SELECTED DRAWING: Figure 2 【課題】ESRの上昇を抑制し、高い信頼性を実現できる固体電解コンデンサを提供する。【解決手段】固体電解コンデンサは、平膜状の陽極用電極箔の表面に誘電体層、および、固体電解質層が順次形成された複数の平膜状のコンデンサ素子と、複数の平膜状の陰極用電極箔とを交互に積層して形成されたシート積層体と、シート積層体を封止する絶縁性樹脂と、を備える。それぞれのコンデンサ素子と陰極用電極箔との間には、平面視において、環状に形成された絶縁性を有するダムと、ダムに囲まれる領域内に、導電性を有する第1接着剤および第2接着剤と、を備える。【選択図】 図2
