Abstract:
1. An electrode for an electric double layer capacitor, comprising: a collector sheet; an electrode forming sheet; a conductive adhesive layer containing carbon black, graphite, and resin component, the conductive adhesive layer provided between the collector sheet and the electrode forming sheet; and not fewer than 100,000 dimples formed on a surface of the collector sheet per 1 cm the dimples having: outermost diameters in a range from 4 to 10 μm; depths in a range from 4 to 15 μm; area percentage of not more than 50% with respect to the entire surface of the collector sheet; and a peak value in a particle size distribution of the graphite in a range from 2.6 to 3.2 μm.
