The present invention has an object of providing a porous carbon which can sufficiently adsorb water vapor on a high humidity side.nThe porous carbon of the present invention is characterized in that it has mesopores and micropores, and the water vapor adsorption amount ratio represented by the following formula (1) is 1.8 or more, and particularly, the water vapor represented by the following formula (1) is used. The adsorption amount ratio is preferably 2.0 or more. Further, it is preferable that the amount of water vapor adsorption when the relative humidity is 70% is 50 mg/g or more.nWater vapor adsorption ratio = water vapor adsorption amount at a relative humidity of 90% / water vapor adsorption capacity at 70% relative humidity ‧ ‧ (1) |
