There are provided methods of manufacturing an electric double layer capacitor cell and an electric double layer capacitor and an apparatus for manufacturing an electric double layer capacitor cell. The method of manufacturing the electric double layer capacitor cell includes preparing first and second electrode sheets by printing electrode material onto conductive sheets, respectively, with the exception of regions to be provided as first and second terminal lead-out portions in the conductive sheets; punching the first and second electrode sheets so as to form a plurality of first and second unit electrodes, respectively, each first unit electrode having the first terminal lead-out portion and each second unit electrode having the second terminal lead-out portion; stacking the first and second electrode sheets with a separator interposed therebetween in order that the plurality of first and second unit electrodes are overlapped; and cutting the first and second electrode sheets being stacked into the first and second unit electrodes.
