Abstract
An electric double layer capacitor having polarizable electrodes including activated carbon fibers which are fully activated and have a large specific surface area, and a method for making the same. Each of the polarizable electrodes is composed of an activated carbon element having a surface fiber ratio (total geometric surface area of fabric/total geometric surface area of secondary fibers or strands) of 0.01 or more. Each activated carbon element is in the form of a woven fabric, nonwoven fabric, felt or the like including activated carbon fibers.
