Abstract
An electrode excellent in high-rate discharge characteristics is provided by increasing the adhesive strength of the conductive core material to the sintered nickel porous body which form the sintered type substrate. The electrode of the present invention uses a sintered substrate containing a part wherein the diameter of the pores of the sintered nickel porous body becomes successively smaller from the joining interfaces of the conductive core material toward the outside surfaces of the substrate. The region wherein the diameter is greater than in other parts preferably ranges within about 1/5 of the substrate thickness starting from both surfaces of the core material toward the outside surfaces of the substrate.
