An electrolytic capacitor with a further lowered impedance is provided. In the electrolytic capacitor in accordance with the present invention, respective currents directed opposite from each other flow through anode and cathode vias extending along the thickness of a substrate. The anode vias are lopsidedly located in a marginal area of an anode electrode pattern, and thus are disposed significantly close to the cathode vias formed in a cathode electrode pattern disposed close to the anode electrode pattern.
