To provide a metal porous body with low manufacturing cost, high active material utilization factor, and high discharge performance by vertically arranging the longest axis in the external shape of a metallic material on a metal flat plate.
A metallic material 2 and a binder mainly comprising resin are mixed with a solvent, and they are stirred to form slurry, the slurry is applied to a metal flat plate 1, magnetic field is vertically applied to the metal flat plate to let the metallic material 2 stand in the sword blade shape on the metal flat plate 1, and the metallic material 2 is fixed, then sintered. The binder containing no metal salt and a cyclic bond is preferable so that impurities are not left after sintering. An active material is filled in the metal porous body obtained to form a battery electrode.
