An object of the present invention is to provide a porous carbon capable of sufficiently adsorbing water vapor on a high humidity side. SOLUTION: Porous carbon having mesopores and micropores, and having a water vapor adsorption amount ratio shown in the following formula (1) of 1.8 or more, in particular, the following formula (1) It is preferable that the water vapor adsorption amount ratio shown in FIG. Water vapor adsorption amount ratio = water vapor adsorption amount when the relative humidity is 90% / water vapor adsorption amount when the relative humidity is 70% (1) [Selection] Figure 2 |
