摘要： Provided is a porous metal body having higher corrosion resistance than existing porous metal bodies composed of nickel-tin binary alloys and existing porous metal bodies composed of nickel-chromium binary alloys. The porous metal body contains at least nickel, tin, and chromium. An example of a method of producing such a porous metal body is a method including a conductive-coating-layer formation step of forming a conductive coating layer containing chromium on a surface of a porous base formed of a resin material; a metal-layer formation step of forming a nickel layer and a tin layer in any order on a surface of the conductive coating layer; a removal step of removing the porous base; and a diffusion step of, by a heat treatment, causing interdiffusion of metal atoms between the nickel layer and the tin layer and diffusing chromium contained in the conductive coating layer into the nickel layer and the tin layer.

摘要： A capacitor has a positive electrode 10, a negative electrode 20, and a solid electrolyte layer arranged between the electrode layers 10 and 20. At least one 10 (20) of the electrode layers of this capacitor 100 has an Al porous body 11, and an electrode body 12 (13) held in this Al porous body 11 to polarize the electrolyte. The oxygen content in the surface of the Al porous body 11 is 3.1% by mass or less. The matter that the oxygen content in the surface of the Al porous body 11 is 3.1% by mass or less is equal to the matter that a high-resistance oxide film is hardly formed on the surface of the Al porous body 11. Thus, this Al porous body 11 makes it possible to make the current collector area of the electrode layer 10 (20) large so that the capacitor 100 can be improved in capacity.
