Abstract
Abstract An adsorbent having high adsorption characteristics and high heat conductivity, which comprises a heat conductive sheet and at least one adsorbing sheet provided on at least one surface of the heat conductive sheet in contact therewith and which can perform a removal or supply of a heat through the heat conductive sheet to improve the adsorption or desorption efficiency, and an assembly comprising at least two adsorbents arranged in layers so as to form spaces between the adjacent adsorbents.
