1. A method of producing a film-like electrode structure for an electronic device, the method comprising the steps of:
producing carbon nanotubes in a flowing gas phase;
preparing a dispersion having the carbon nanotubes dispersed in a liquid medium with at least one of a powdered active carbon dispersed in the liquid medium and carbon black dispersed in the liquid medium;
filtering the dispersion with a filter to obtain a film of an agglomerate electrically conductively and structurally consisting essentially of the carbon nanotubes agglomerated with at least one of the powdered active carbon and the carbon black; and
drying the film of the agglomerate,
wherein the step of producing the carbon nanotubes comprises feeding a carbon starting material containing a catalyst and a carbon source into a chamber and synthesizing the carbon nanotubes in the chamber by pyrolysis of the carbon source,
wherein the average length of the carbon nanotubes based on electron microscopic observation is at least 1 μm, and
wherein the volume resistivity of the carbon nanotubes is not more than 2×10-2 Ω·cm.
