摘要： An electrode-forming composition for providing an activated carbon electrode for an electric double layer capacitor is provide by blending activated carbon, a vinylidene fluoride polymer and a solvent including a plasticizer in addition to a good solvent for the vinylidene fluoride polymer. By applying the electrode-forming composition onto an electroconductive substrate, and selectively removing the solvent preferably by a combination of extraction of the plasticizer with a poor solvent for the vinylidene-fluoride polymer and evaporation of the solvent, it is possible to obtain an activated carbon electrode (polarizable electrode) that has an activated carbon electrode layer exhibiting good adhesion onto the electroconductive substrate and a good flexibility, and therefore has good processability. By using the activated carbon electrodes as polarizable electrodes, it is possible to provide an electric double layer capacitor having improved reliability.
