Claim 0:
1. A humidity control element comprising:
a plurality of flat plate members that are stacked in a state where a first flow path through which a first fluid flows is formed in a space between a pair of the plurality of the flat plate members and a second flow path through which a second fluid flows is formed in a space between another pair of the plurality of the flat plate members,
wherein the first flow path and the second flow path are set in a stacking direction of the flat plate members,
heat is exchangeable between the first flow path and the second flow path via the flat plate members,
each of the plurality of flat plate members is formed of any one material of a resin, paper, glass, a metal, and a ceramic, or a composite material obtained by combining two or more materials selected from these materials, and
a dehumidifying flow path is formed by applying a mixed liquid comprising a metal organic framework MIL-101 (Cr) containing chromium as a hygroscopic material adsorbing and desorbing moisture, an acrylic polymer material functioning as a binder, and a urethane-based polymer material as a thickener on any one of an inner surface of the first flow path and an inner surface of the second flow path,
wherein proportions of MIL-101 (Cr) as the hygroscopic material, the acrylic polymer material, and the urethane-based polymer material are, when a total solid content thereof is 100% by mass, MIL-101 (Cr) is 58% by mass to 80% by mass, the urethane-based polymer material is 1% by mass to 2% by mass, and a remainder is the acrylic polymer material.
