Abstract
In an electrode according to the present invention including a three-dimensional network aluminum porous body as a base material, the electrode is a sheet-shaped electrode, and a cell of the three-dimensional network aluminum porous body has an elliptic shape having a minor axis in the thickness direction of the electrode in a cross section parallel to the longitudinal direction and thickness direction of the electrode, and a cell of the three-dimensional network aluminum porous body has an elliptic shape having a minor axis in the thickness direction of the electrode in a cross section parallel to the width direction and thickness direction of the electrode. The electrode is preferably obtained by subjecting the three-dimensional network aluminum porous body to at least a current collecting lead welding step, an active material filling step and a compressing step.
