Abstract
A solid electrolytic capacitor is constructed by a capacitor element body, a metal rod extended through the central part of the element body, an anode member, and an insulating layer placed between the flange part of the anode member and the element body. The capacitor element body consists of a chip-like porous solid formed by shaping and sintering rectifying metal particles, the porous solid having a dielectric layer and a solid electrolytic layer both being formed thereon. The anode member includes a protruded part and a flange part, the end face of the protruded part being brought into contact and connected with one of the end faces of the metal rod. A method of manufacturing solid electrolytic capacitors thus constructed is also disclosed.
