PROBLEM TO BE SOLVED: To provide a small and high capacity electric double layer capacitor inexpensively by a convenient process. SOLUTION: A porous conductive film 1 is employed as a current collector and since it is used as a filter for low pressure suction filtering 6 polarizable electrode solution 5 where carbon nanotubes 2 and micropowder active carbon 3 are dispersed uniformly using an ultrasonic wave and a substance containing the carbon nanotubes 2 is laminated on the porous conductive film 1, contact area between the current collector and the carbon nanotubes can be increased. In the vicinity of a thin hole 4, a contact surface only between the current collector and the carbon nanotubes 2 is constituted and contact resistance between the current collector and the polarizable electrode is reduced. Furthermore, a good contact surface having no void on the interface is formed by suction force. COPYRIGHT: (C)2006,JPO&NCIPI
