Abstract
A solid electrolytic capacitor minimized in both equivalent serial resistance (ESR) and equivalent serial inductance (ESI) by eliminating redundant space created by its electrode is presented. The solid electrolytic capacitor includes a capacitor element including mainly of a positive electrode body, having a positive electrode lead embedded therein, and made of any form of a valve metal, such as a net, a sheet, a foil, and modifications thereof with a rough surface; a positive electrode terminal connected to the positive electrode lead; a negative electrode terminal connected to a negative electrode layer; and a housing resin coated by molding. This improves the installation efficiency of the capacitor element, and contributes to the small, thin structure of the solid electrolytic capacitor.
