To provide a spherical composite carbon material having further improved adsorption capacity such as gas adsorption capacity.SOLUTION: A composite carbon material according to the present invention contains an activated carbide of cellulose nano-fiber in spherical particles made of activated carbide of a phenol resin. A composite carbon material can be obtained having a specific surface area larger than a carbide made of a phenol resin alone, and a composite carbon material having further improved adsorption capacity such as gas adsorption capacity can be obtained.SELECTED DRAWING: None 【課題】ガス吸着能など吸着能力を一層向上した球状の複合炭素材料を提供することを課題とする。【解決手段】本発明に係る複合炭素材料は、フェノール樹脂の賦活された炭素化物からなる球状の粒子内に、セルロースナノファイバーの賦活された炭素化物が含有されていることを特徴とする。フェノール樹脂単独の炭素化物よりも高比表面積となった複合炭素材料を得ることができ、ガス吸着能などの吸着能力が一層向上した複合炭素材料を得ることができる。【選択図】なし
