PROBLEM TO BE SOLVED: To provide a solid electrolytic capacitor using a conductive polymer for a cathode layer, a high capacity impregnation rate, a small size, a large capacitance and excellent electrical characteristics, and a method for manufacturing the same. SOLUTION: Forming a cathode layer composed of a normal temperature molten salt having a decomposition point of at least 300 ° C. exemplified by 1-butylpyridinium salt and / or 1-ethyl-3-methylimidazolium salt and a conductive polymer The cathode layer is formed by impregnating a capacitor element with a room temperature molten salt, and then forming a conductive polymer or polymerizing a mixture of a room temperature molten salt and a conductive polymer monomer. Let it form. [Selection figure] None |
