PROBLEM TO BE SOLVED: To provide an electrode for battery easily manufacturable and superior in capacity by forming a conductive plate, such that even if a collector is welded to a conductive plate, the conductive plate is not bent so that the filled amount of active material of a porous body with three-dimensional net-like structure will not be lowered. SOLUTION: After a groove part 12 is formed in one end part of a band- shaped foam resin 11 at the center part in thickness direction along the longitudinal direction of the foam resin, and a band-shaped conductive metal plate 13 is fixedly inserted into the groove part 12. After carbon powder is applied to the foam resin, a nickel plating is applied thereto, and the band-shaped foam resin 11 is baked at a specified temperature to remove the skelton of the band- shaped foam resin 11. Thus, a nickel porous body 10, having hollow skelton nickel metal and nickel-plated band-shaped metal plate, is formed integrally with each other. After filling an active material slurry into the nickel porous body 10, the nickel porous body is dried, rolled into a specified thickness, and then cut to a specified dimension to provide a nickel positive electrode. |
