The surface of sintered metal made of tantalum or the like and having an open porosity ratio of more than 75% is oxidized so as an oxide film 12 made of tantalum pentoxide or the like is deposited thereon. The cavities of the metal are filled with an electrically conductive material 13. Then the metal is wound around a lead wire and made into a desired shape and size. The silver layer is formed on the porous metal body. Because the surface area ratio of the sintered metal is large, a large capacity is obtained.
