Abstract
A functional material is provided and includes a porous carbon material derived from a plant-derived material as a raw material, wherein a bulk density of the porous carbon material is in a range of 0.2 grams/cmto 0.4 grams/cm, a value of a cumulative pore volume in a range of 0.05 μm to 5 μm in pore size of the porous carbon material based on a mercury press-in method is in a range of 0.4 cmper 1 gram of the porous carbon material to 1.2 cmper 1 gram of the porous carbon material, and a value of a pore volume of the porous carbon material based on an MP method is in a range of 0.04 cmper 1 cmof the porous carbon material to 0.09 cmper 1 cmof the porous carbon material.
