Abstract: An object of the present invention is to provide a capacitor excellent in reliability, of which charge-discharge characteristics are hardly deteriorated. The capacitor of the present invention includes: a capacitor element including a positive electrode and a negative electrode; and a case that stores the capacitor element together with an electrolytic solution, wherein at least one of the positive electrode and the negative electrode contains activated carbon, and a sum of volumes per unit weight of pores having a pore diameter of from 30 Å to 100 Å inclusive among pores of the activated carbon is 0.2 cm3/g or more.

Abstract: A capacitor electrode includes a substrate having electrical conductivity, a conductive layer formed on a surface of the substrate, and an electrode layer formed on the conductive layer. The electrode layer is allowed to adsorb and desorb ions on a surface thereof. The conductive layer contains flake graphite. A density of the conductive layer is greater than 1.1 g/cm3. An average particle size D50 of the flake graphite, which is measured by using a dynamic light scattering method, is less than or equal to 10 μm.
