Abstract
An electric double-layer capacitor includes a casing, a pair of porous electrodes disposed within the casing, a permeable separator sandwiched between both the porous electrodes, and an electrolytic liquid formed of an organic solvent, injected into the casing and permeating the porous electrodes and the separator. The separator is formed from an aggregate of cellulose fiber having a surface modified by an organic solvent thereby.
