Abstract
A solid electrolytic capacitor is disclosed whose semiconductor layer has improved mechanical strength and which has LC characteristics stable at a low level, and a method for preparing the same is also disclosed. The solid electrolytic capacitor comprises: an anode body with an element lead wire partially inserted therein, said anode body made of a sintered valve metal and having a large number of voids; a dielectric layer formed over the surface of the anode body; a semiconductor layer including a porous phase so formed as to cover the dielectric layer and extend into the voids and an electrically conductive polymer so formed as to fill a plurality of through-holes of the porous phase with the electrically conductive polymer; a cathode body formed on the surface of the semiconductor layer.
