<P>PROBLEM TO BE SOLVED: To provide an electrode substrate and an electrode preventing contact of a positive electrode and a negative electrode, when they are spirally wound by forming the skeleton of three-dimensional net structure so as to make it less apt to pass through a separator. <P>SOLUTION: An electrode substrate 10 for an alkaline secondary battery has three-dimensional net structure, in which the inside is hollow and the tip part 12 of the skeleton 11 exposed to the surface of foam nickel has a spherical or hemispherical outer shape. The spherical or hemispherical outer shape is formed, in such a way that a tip part 12a of a skeleton 11a exposed to the outside of foam resin 10a having three-dimensional net structure is deformed to a spherical or hemispherical tip part 12b of a skeleton 11b exposed to the outside of foam resin 10b by heat treatment, and the foam resin 10b is made electrically conductive; and after electrolytic nickel plating is applied, the foam resin is decomposed and removed by heating. <P>COPYRIGHT: (C)2011,JPO&INPIT |
