To stably provide a high capacity electrode for capacitors.SOLUTION: A capacitor 10 has electrodes 2, 3 for capacitors that include: a metal porous body having a three-dimensional network structure; and first carbon which is filled in gaps of the metal porous body. The first carbon includes graphenes. In the graphenes, The average number of laminated graphene sheets is 10 layers or less, the interlayer distance between graphene sheets changes randomly and has a crimping or folding structure, and the distance between the surfaces of 002 planes of graphene calculated from the X-ray diffraction profile is 0.338 nm or more.SELECTED DRAWING: Figure 1 【課題】高容量のキャパシタ用電極を安定して提供する。【解決手段】キャパシタ１０において、キャパシタ用電極２、３は、三次元網目構造を有する金属多孔体と、金属多孔体の空隙に充填された第１カーボンと、を含む。第１カーボンは、グラフェンを含む。グラフェンは、グラフェンシート積層体の平均積層数が、１０層以下であり、グラフェンシート同士の層間距離がランダムに変化し、縮れ構造もしくは折りたたみ構造を有し、Ｘ線回折プロファイルから算出されるグラフェンの００２面の面間距離が、０．３３８ｎｍ以上である。【選択図】図１
