Abstract
Provided is a method for producing an activated carbon for an electric double layer capacitor electrode comprising adjusting a carbon material (including a calcined product of a carbon material) in particle size, followed by mixing the carbon material with an alkali activator, and then activating the mixture, wherein the mixing is carried out so that the particle size distribution composed of particles with a size of 300 μm or greater in the mixture of the carbon material and alkali activator is 5 percent or less so that the mixing state of the carbon material and alkali activator can be improved, resulting in a reduction in the ratio of the alkali activator.
