Abstract
In an electric double layer capacitor having a pair of polarizable electrodes containing activated carbon and auxiliary materials for giving electric conductivity to the polarizable electrodes, the auxiliary materials include at least two carbon materials such as epitaxially grown carbon fiber and granular graphite. An electric double layer capacitor having small internal resistance, large electrostatic capacitance and small variations of internal resistance and capacitance is realized by the auxiliary materials.
