[Problem] Adsorption heat cycle performance is determined by how quickly a large amount of moisture absorption is obtained, in other words, by the amount of moisture absorption and the rate of moisture absorption. However, conventional hygroscopic materials cannot achieve sufficiently both an excellent amount of moisture absorption and an excellent rate of moisture absorption, thereby limiting adsorption heat cycle performance. Due to said limitation, device miniaturization is difficult, leading to a delay in supply. In particular, a vehicle-mounted adsorption refrigeration cycle having a limited installation capacity has a significant problem of insufficient performance of hygroscopic materials, so that commercialization thereof is hindered. The objective of the present invention is to provide a hygroscopic material that achieves both high hygroscopicity and a high rate of moisture absorption. [Solution] This high-speed moisture-absorbing/desorbing polymer is an organic polymer characterized by containing 2.0-8.0 mmol/g of a carboxyl group in which a counter cation is an organic onium ion, and having a crosslinked structure, wherein all the alkyl groups contained in the organic onium ion have 1-4 carbon atoms.
