    • A metallic porous body comprises a metallic framework having a three-dimensional network with a continuous-pore structure formed by linking sub-stantially polyhedral cells. The substantially polyhedral cells have an average cell diameter of about 200 to about 300 &mgr;m and an average window diameter of about 100 to about 200 &mgr;m. The metallic porous body can be obtained by the following method, for instance: First, a plastic porous body is provided that has an average cell diameter of about 200 to about 300 &mgr;m and an average window diameter of about 100 to about 200 &mgr;m. Second, a conductive layer is formed on a surface of the framework of the plastic porous body to produce a conductive porous body having a resistivity of about 1 k&OHgr;·cm or less. Finally, a continuous metal-plated layer is formed on a surface of the conductive layer by electroplating, with the conductive porous body serving as the cathode. The above-mentioned current collector is provided by filling an active material into the pores of the metallic porous body.

    • A conductive porous body that has a conductive layer almost free from impurities and that enables a metallic porous body having extremely low resistance to be produced with high productivity and production efficiency, and a metallic porous body and a battery plate both produced by using the conductive porous body. The conductive porous body has a nickel conductive layer formed on the surface of the framework of a plastic porous body having a continuous-pore structure. The conductive layer is formed by the deposition of nickel from an aqueous solution containing nickel compounds with the use of a reducing agent containing titanium compounds. The metallic porous body can be obtained by forming a continuous metal-plated layer on the surface of the framework of the conductive porous body. The metal-plated layer is formed by electroplating with the conductive porous body serving as the cathode. The battery plate consists mainly of the metallic porous body.
