Abstract
The purpose of the present invention is to provide: an electric double-layer capacitor, a lithium ion secondary battery, and a lithium ion capacitor, each of which has excellent cycle characteristics; an electrode material which is capable of providing the electric double-layer capacitor, the lithium ion secondary battery, and the lithium ion capacitor; and a composite which is used in the electrode material. The composite of the present invention is a composite produced by compositing from 0.5 to 5 parts by mass of nitrogen atom-containing conductive polymer per 100 parts by mass of porous carbon material. The composite of the present invention is a composite where the peak area ratio (nitrogen/carbon ratio) of peak area derived from nitrogen atoms to peak area derived from carbon atoms in the spectrum by X-ray photoelectron spectroscopy becomes 0.005 to 0.05.
