Summary:To provide a material that has excellent handleability and processability, and that when used as a support for a different material, enables support of the different material up to an inner part thereof.SOLUTION: A carbon sheet of this invention contains carbon nanotubes and has a porosity of 5% or more and 90% or less. The carbon sheet of this invention preferably includes: a porous substrate made from carbon; and the carbon nanotubes, attached to the porous substrate. The carbon nanotubes contained in the carbon sheet are preferably single-layered carbon nanotubes. Moreover, the carbon nanotubes contained in the carbon sheet preferably have a nitrogen adsorption specific surface area of 600 m2/g or more.SELECTED DRAWING: None 【課題】本発明は、取り扱い性および加工性に優れると共に、異種材料の担体として使用した際に異種材料を内部まで担持することができる材料を提供することを目的とする。【解決手段】本発明の炭素シートは、カーボンナノチューブを含み、空隙率が５％以上９０％以下であることを特徴とする。また、本発明の炭素シートは、炭素製の多孔質基材と、前記多孔質基材に付着した前記カーボンナノチューブとを備えることが好ましい。炭素シートに含まれるカーボンナノチューブは、単層カーボンナノチューブであることが好ましい。また、炭素シートに含まれるカーボンナノチューブは、窒素吸着比表面積が６００ｍ２／ｇ以上であることが好ましい。【選択図】なし
