Abstract
A solid electrolytic capacitor that is able to maintain a high capacitance and low ESR, and also exhibits a high degree of heat resistance. The solid electrolytic capacitor 10 comprises at least an anode body 11 composed of a porous material, a dielectric layer 12 formed on the surface of the anode body 11, and a cathode body 13b, wherein the solid electrolytic capacitor has a solid electrolyte layer 13a formed in contact with the dielectric layer 12, the solid electrolyte layer 13a comprises at least a hydroxy compound having three or more hydroxyl groups, and the hydroxy compound has a melting point of not less than 170° C.
