The purpose of the present invention is to provide an adsorbing/desorbing material which comprises a porous carbon material and which can smoothly conduct the adsorption and desorption of gas or liquid. An adsorbing/desorbing material that comprises a porous carbon material which is provided with micropores and mesopores and/or macropores, these three kinds of pores being surrounded by carbonaceous walls, and in which the micropores are formed so as to connect to the mesopores and/or the macropores, characterized in that x falls within a range specified by the formula 1.0×10-5 = x = 1.0×10-4, and x and y satisfy formula (1) y = 1.67×10-1x+ 2.33×10-6 ··· (1) [wherein x is a relative pressure (P/P0) as determined using nitrogen as an adsorbate gas at 77K, and y is a mass transfer coefficient (Ksap) as determined similarly]. |
