In a rechargeable battery in which an electrode plate group (10) obtained by superimposing a positive electrode plate (1), in which positive electrode material (1a) is attached to a positive electrode current collector (1b), and a negative electrode plate (2), in which negative electrode material (2a) is attached to a negative electrode current collector (2b), with a separator (3) therebetween is accommodated in a battery container (4) together with electrolyte, the current collectors (1b, 2b) of the electrode plates (1, 2) are respectively projected at opposite ends of the electrode plate group (10), forming by themselves flat planes (11, 12) by being pressed, and current collecting plates (8, 9) are joined to these flat planes (11, 12). <IMAGE> |
