ABSTRACT:
In an electric double layer capacitor, a pair of conductive layers are formed on a pair of electrically insulating substrates, respectively.
A pair of polarizable electrodes are sandwiched between the conductive layers and an ionically conducting separator is interposed between the polarizable electrodes. The polarizable electrodes are preferably made of activated carbon/polyacene composite.
This invention realizes to form a plurality of elements electrically insulated on the same substrate, because it is possible to form the electric double layer capacitors using the electrically insulated substrate. More, it is possible to arrange a plurality of elements in line on the same substrate by designing conductive layers forming on the electrically insulating substrates, so that the electric double layer capacitors of which breakdown voltage is high and the height is low are obtained.
