PROBLEM TO BE SOLVED: To provide a solid electrolytic capacitor which is made low in ESR, as well as, has superior heat resistance. SOLUTION: In the solid electrolytic capacitor with a solid electrolyte including a mixture of an ethylene dioxythiophene derivative having an alkoxy group and a propylene dioxythiophene derivative having an alkoxy group as a monomer and a conductive high polymer layer which is a polymer using alkoxy aromatic sulfonic acid ions as a dopant, is manufactured, the mixing ratio of the ethylene dioxythiophene derivative, having the alkoxy group and the propylene dioxythiophene derivative having the alkoxy group, is preferably, 3:2 to 4:1 in terms of the ratio by weight.
