Summary:To provide an adsorption device which can favorably absorb moisture from an airflow generated by a blower or desorb moisture to the airflow in a simple structure, and which can favorably adsorb and desorb carbon dioxide.SOLUTION: An adsorption device adsorbing and desorbing a prescribed component contained in an airflow sent from a blower comprises: a carbon dioxide adsorbent which repeatedly adsorbs and desorbs carbon dioxide; and a hygroscopic material which adsorbs and desorbs moisture. The carbon dioxide adsorbent includes a high polymer of a chemical constitution where functional groups including an amine group being at least a primary amine group are combined, is formed to be porous to adsorb and desorb moisture, and can desorb carbon dioxide at 40°C or more and desorb moisture at a temperature less than 40°C. The hygroscopic material can desorb moisture at a temperature less than 100°C, in which the amount of moisture adsorption thereof is more than the amount of moisture adsorption of the carbon dioxide adsorbent at a balanced steam pressure less than 1,600 Pa.SELECTED DRAWING: Figure 4 【課題】 簡素な構成で、送風器で発生した空気流に対して、良好に吸放湿できるとともに、二酸化炭素の良好な吸着および放出を可能とする。【解決手段】 吸着デバイスは、送風器から送風される空気流に含まれる所定成分を吸着および放出するために用いられ、二酸化炭素を繰り返し吸着および放出する二酸化炭素吸着材と、水分を吸着および放出する吸湿材と、を備える。二酸化炭素吸着材は、少なくとも１級アミン基であるアミン基を含む官能基が結合した化学構造を有する高分子化合物を含み、多孔質状に形成され、水分を吸着および放出するものであって、４０℃以上の温度で二酸化炭素を脱離可能、かつ、４０℃未満の温度で水分を放出可能とする。吸湿材は、１００℃未満の温度で水分を放出可能とし、かつ、水蒸気平衡圧１，６００Ｐａ未満での水分の吸着量が、二酸化炭素吸着材の水分吸着量以上である。【選択図】 図４
