Abstract
An electrode plate for a battery is constructed from a porous metal body having at least one low-porosity part selectively arranged therein. A porous resin core is coated with a paste having a metal component, passed through rolls provided with at least one recess to thereby form at least one low-porosity part and sintered. The resultant electrode plate for battery is not only ensured with respect to strength and capable of improving battery performance but also advantageous in that it is available at lowered cost and free from apprehension of supply of raw materials.
