NOVELTY - The electrode (2,3) comprises carbon nanotube, grapheme and ionic liquid. The three-dimensional mesh shaped metal porous main portion is adapted to hold the carbon nanotube, the graphene, and ionic liquid in hole. The ratios of the total amount of the carbon nanotube and the graphene with respect to the quantity of the ionic liquid is 10 mass% to 90 mass%. The mass ratio between carbon nanotube and the graphene is in the range of 3:7-7:3. The graphene is in the range of 0.34 nm-100 nm of average thickness. The carbon nanotube is in the range of average length 100 nm-2000 micrometers. USE - Electrode for electrical storage device such as electrical double layer capacitor (claimed) for use in electric equipment. ADVANTAGE - The contact area of a carbon nanotube and an ionic liquid is increased and the electrostatic capacitance and a cell voltage are improved. The energy density that is stored electrically is improved. The rate characteristic of electrical storage device is improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the method of manufacturing electrode for electrical storage device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the cell of the electrical double layer capacitor. Separator (1) Positive electrode (2) Negative electrode (3) Upper-cell case (7) Lower cell case (8)
