<p>PROBLEM TO BE SOLVED: To provide an electric double layer capacitor which can be reduced in size and cost, can prevent the positional deviations between polarizable electrodes and collectors, and can secure a high capacitance in an early stage in the charging and discharging cycle of the capacitor. SOLUTION: This electric double layer capacitor 1 is constituted by interposing a separator 3 between a pair of polarizable electrodes 2 and 2 and providing at least a set of cells 6 in which collectors 4 are respectively laminated upon the surfaces of the electrodes 2 opposite to the separator 3. Then at least one projecting section 7 is formed on the surfaces of the electrodes 2 upon which the collectors 4 are laminated and, at the same time, the projecting sections 7 are inserted into through holes 8 made through the collectors 4.</p> |
