There is provided an electric double layer capacitor including: a multilayer electric double layer capacitor cell including first and second electrodes facing each other with an ion-permeable separator interposed therebetween; and an insulating tape with which to enclose an outer surface of the multilayer electric double layer capacitor cell and having a plurality of pores. In the electric double layer capacitor, movements between the first and second electrodes and the ion-permeable separator are minimized so that the area of the facing surfaces of the first and second electrodes increases. Accordingly, high capacitance may be achieved. In addition, the pores formed in the insulating tape facilitate the path of an electrolyte so that the impregnation of the electrolyte into the multilayer electric double layer capacitor cell is thereby facilitated.

There is provided a chip-type electric double layer capacitor cell and a method of manufacturing the same. The chip-type electric double layer capacitor cell includes a separator folded to include first and second folded portions with first and second open portions formed in opposite directions by the first and second folded portions, and first and second electrodes inserted into the first and second open portions. The positions of the first and second electrodes are fixed by the first and second folded portions of the separator, and accordingly, the appropriate arrangement of the plurality of first and second electrodes is facilitated. A short circuit between the first and second electrodes is avoided to thereby increase the capacitance of the chip-type electric double layer capacitor cell.
