Abstract
An excellent hygroscopic material containing a temperature responsive polymer, which can efficiently conduct heat, and hence has water release properties of absorbed water is realized. The hygroscopic material containing a polymer gel containing a temperature responsive polymer whose affinity with water reversibly changes in response to temperature stimulation and a thermally conductive filler is used.
