Abstract
The present invention achieves a moisture absorbing material which enables efficient dehumidification without supercooling or large heat quantity; and a dehumidifier in which the moisture absorbing material is used. The moisture absorbing material can be a dried product of a polymer gel in which an interpenetrating polymer network structure or a semi-interpenetrating polymer network structure is formed by (a) a stimuli-responsive polymer whose affinity with water changes reversibly in response to an external stimulus and (b) a hydrophilic polymer.
