PROBLEM TO BE SOLVED: To fully inhibit that an ESR in a solid electrolytic capacitor rises and a leakage current increases by fully alleviating a pressure to be applied to the solid electrolytic capacitor, suppressing that the exfoliation arises between each layer in a cathode, a contact area between the conductive particles, such as a carbon contained in each layer of the cathode and a silver, etc., is reduced or a crack arises in the interface of the electrolyte layer and the dielectric layer, and in the dielectric layer when a housing body made of an insulating resin is provided for covering the whole solid electrolytic capacitor is provided. SOLUTION: The solid electrolytic capacitor comprises an anode 1 made of a valve action metal or an alloy composed of a valve action metal as a principal component, a dielectric layer 2 formed by anodizing the anode, and a cathode 4. In its cathode, conductive particles A and B having a stress relaxation property are made to be contained. COPYRIGHT: (C)2006,JPO&NCIPI
