とができる。Next, the action and effect will be explained. The multilayer electric double layer capacitor according to the present invention having the above-mentioned configuration has a capacitor element A and a capacitor element B stacked in series with the second electrode plate 6 in between, as shown in FIG. , are housed and integrated by the dish-shaped first electrode plate 1 and third electrode plate 12, which have the functions of external connection terminals and an exterior case, so the number of steps is not much different from that of assembling a unit cell. As a result, a self-supporting multilayer electric double layer capacitor having the same functions as a conventional multilayer electric double layer capacitor as shown in FIG. 4 can be manufactured at low cost.
