Abstract
A dehumidifying device configured such that a dehumidifying material having absorbed moisture can efficiently release moisture. The dehumidifying device carries out dehumidification with a polymeric moisture-absorbing material that (i) exhibits hydrophilicity in a temperature range equal to or lower than a temperature sensitive point which is a given temperature and (ii) exhibits hydrophobicity in a temperature range higher than the temperature sensitive point. The dehumidifying device includes: a substrate to which the polymeric moisture-absorbing material is fixed; a heat generating member which heats, to the temperature range higher than the temperature sensitive point, the polymeric moisture-absorbing material that has absorbed moisture; and a moisture absorbing unit motor which rotates the substrate, so that the moisture, which has been absorbed by the polymeric moisture-absorbing material that is heated to the temperature range higher than the temperature sensitive point, is released as a waterdrop by a centrifugal force.
