PROBLEM TO BE SOLVED: To provide a solid electrolytic capacitor that can prevent mechanical stresses that are applied to a lead wire from being transmitted to the inside of a capacitor element, and at the same time, can improve the electrical characteristics. SOLUTION: A winding-type capacitor element 1 is accommodated into a closed-end outer packaging case 2 made of aluminum or the like, and the inside and entire-periphery surface are covered with an epoxy resin layer 3. The opening part of the outer packaging case 2 is sealed with a sealing body 4 that is composed by combining a hard member 4a with an elastic member 4b. The sealing body 4 is composed by covering the bottom and side surfaces of the hard member 4a, such as a bakelite plate with the elastic member 4b, such as butyl rubber. In the sealing body 4, a through-hole 6 for inserting a lead wire 5 is formed. Then, arrangement is made so that the cylinder part 5a of the lead wire 5 is positioned in the through-hole 6.
