PROBLEM TO BE SOLVED: To provide an electrode manufacturing method by which the service life of a battery is improved by preventing falling out of an active material and production is facilitated by enhancing strength of an electrode, and a secondary battery having the electrode manufactured thereby. SOLUTION: When an electrode of a secondary battery is manufactured, holes 3 are formed at a prescribed interval in a material by covering a steel surface with nickel, and an active material holding body 2 is formed, and after an active material 1 of the battery is applied to the active material holding body 2 in a slurry condition, a secondary active material holding body 4 is deposited. |
