Abstract

A solid electrolytic capacitor with high withstand voltage while maintaining low equivalent series resistance characteristic, and the manufacturing method thereof are provided. A separator is intervened between the anode body and the cathode body. The separator holds conductive polymer particles and intervenes a layer of the conductive polymer particles between the anode body and the cathode body. The separator contains manila fiber, esparto fiber, or rayon fiber and has the air resistance of 0.35 [s/100mL] or more. This solid electrolytic capacitor is manufactured by an element formation process of forming an element having an anode body having a dielectric film, a cathode body, and a separator by making the anode body and the cathode body to face each other via the separator; and a solid electrolyte layer formation process of impregnating the capacitor element with a conductive polymer dispersion in which conductive polymer particles are dispersed.
