Patent ID: 8404032

Claim:
A humidity-conditioning sheet comprising a sheet-shaped humidity-conditioning layer, wherein the layer is formed by bonding humidity-conditioning particles containing a silicon compound with thermoplastic resin powder, said humidity-conditioning particles reversibly adsorbing and desorbing moisture, wherein the humidity-controlling sheet is a laminated humidity-controlling sheet prepared by laminating a base material sheet composed of an air-permeable material on at least one of the surfaces of the humidity-conditioning layer so that the base material sheet is integrated with the humidity-conditioning layer, wherein the humidity-conditioning particles have an average particle diameter of 5 to 1,000 μm, wherein a weight ratio of the thermoplastic resin powder to the humidity-conditioning particles which constitute the humidity-conditioning layer is 1/4 to 4/1, and wherein the humidity-conditioning layer has a void ratio of 5% or more.
