Disclosed is an electrode for secondary batteries which is obtained by filling pores of a three-dimensional metal porous body (1) with an active material (2). By forming a metal-rich layer (3), which has a higher metal density than the other portions, in a position other than the surface portion in the thickness direction of the three-dimensional metal porous body, the metal-rich layer is caused to have a current collecting property. By optimizing the position of the metal-rich layer, there can be obtained an electrode for secondary batteries which is excellent in both short-circuit resistance and current collecting property.
