<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing an electrode for a secondary battery of a high-safety tab-less structure in a simple method, and a secondary battery equipped with an electrode of a tab-less structure excellent in safety. <P>SOLUTION: An active material layer 2 is coated on a collector 1 with either end part exposed. A width of a first unformed part 1a at one end of the collector 1 is formed narrower than a second unformed part 1b at the other end. Next, a porous film 3 is formed on the collector 1 so as to cover the active material layer 2. Here, the porous layer 3 is formed so as to cover an end face of the active material layer 2 at the first unformed part 1a, and at the same time, to expose a part of the collector 1 at the second unformed part 1b. <P>COPYRIGHT: (C)2008,JPO&INPIT |
