Abstract
A hygroscopic composite material comprising a humidity absorbing body having hygroscopic fillers in its basic material and a porous body having many micropores. This hygroscopic composite material retains its hygroscopicity for a long period of time by enhancing its humidity absorbing function by generating free water in the porous body and by discharging the free water.
