Abstract
A solid electrolytic capacitor includes a capacitor element and an outer shell, made of an insulating resin, that covers the capacitor element. The capacitor element has a winding portion that is formed by rolling an anode foil with a dielectric oxidized film formed on its surface, a cathode foil, and a separator that is sandwiched between the anode foil and the cathode foil, and a conductive polymer layer is formed between the anode foil and the cathode foil. An anode lead wire electrically connected to the anode foil, and a cathode lead wire electrically connected to the cathode foil extend from the winding portion, penetrate the outer shell, and are respectively connected to an anode electrode terminal and a cathode electrode terminal that are arranged on a surface of the outer shell.
