Abstract

An electrode active material for capacitors contains a porous carbon material. The porous carbon material has a BET specific surface area of 800 m/g or more. An X-ray diffraction image of the porous carbon material with CuKα rays has a peak Pat 2θ=40° to 50°, and the peak Pincludes a component of a peak Pattributed to a (111) plane of diamond crystals. When the X-ray diffraction image has a peak Pattributed to a (002) plane of graphite, a ratio of an intensity Iof Pto an intensity Iof P(I/I) is 3.0 or less.
