Abstract
An electrical double-layer capacitor electrode with excellent capacitance characteristics is obtained together with a manufacturing method therefor. Paper-molded sheetof carbon nanotubes is integrated with etched foilconstituting a collector, by means of bumps and indentationsformed on the surface of etched foilto prepare an electrical double-layer capacitor electrode. Alternatively, carbon nanotubesgrown around core catalyst particles on substrateare integrated with etched foilby means of bumps and indentationsformed on the surface of etched foilto prepare an electrical double-layer capacitor electrode. To manufacture these electrodes, this carbon nanotube sheetor substratewith carbon nanotubes grown thereon is laid over bumps and indentationson the surface of etched foil, and the sheet or substrate and the foil are pressed under 0.01 to 100 t/cm2 of pressure to integrate the carbon nanotubes with the etched foil.
