A electrolytic capacitor includes The solid organic conductive material has at least one of organic semiconductor and conductive polymer. In this constitution, an electrolytic capacitor having excellent impedance characteristic, small current leak, excellent reliability, and high dielectric strength is obtained.

Electrolytic capacitor and its manufacturing method

An electrolytic capacitor includes a capacitor element having a positive electrode, a negative electrode, and a solid organic conductive material disposed between the positive and the negative electrode, an electrolyte, a case for accommodating the capacitor element and the electrolyte, and a sealing member disposed to cover the opening of the case. The solid organic conductive material has at least one material selected from organic semiconductor and conductive polymer. The electrolytic capacitor having excellent impedance characteristic, small current leak, excellent reliability, and high dielectric strength.

An electronic component contained in a metal case is attached with an insulation mold at a sealing part and lead wires of the electronic component element are passing through holes on the insulator base, and the end parts of the lead wires are bent in recesses on the insulator base, thereby constituting surface mounting type electronic component.
