    • A humidity-conditioning sheet 10 excellent in reversibility and responsiveness of a moisture adsorbing/desorbing ability of rapidly adsorbing moisture at high ambient humidity and conversely rapidly desorbing adsorbed moisture at low ambient humidity includes a sheet-shaped humidity-conditioning layer 7 formed by bonding together, with a thermoplastic resin powder 4, humidity-conditioning particles 3 which reversibly adsorb and desorb water vapor. The void ratio of the humidity-conditioning layer 7 is 5% or more. Since a ratio of voids 8 formed between the humidity-conditioning particles 3 is high, the voids 8 between the humidity-conditioning particles 3 can be used as water retention spaces for moisture adsorption and desorption, thereby achieving the high reversible moisture adsorbing/desorbing ability and excellent moisture adsorption/desorption responsiveness with the aid of not only the moisture adsorbing/desorbing ability inherent in the humidity-conditioning particles but also the moisture adsorbing/desorbing ability of the voids between the humidity-conditioning particles.
    • 在高环境湿度下快速吸附水分的水分吸附/解吸能力的可逆性和响应性优异的湿度调节片10,并且相反地在低环境湿度下快速解吸吸附的水分包括通过粘合在一起形成的片状调湿层7 ,热塑性树脂粉末4,可逆地吸附和解吸水蒸气的调湿颗粒3。 调湿层7的空隙率为5%以上。 由于调湿颗粒3之间形成的空隙8的比率高,所以调湿颗粒3之间的空隙8可以用作水分吸附和解吸的保水空间,从而获得高可逆的吸湿/解吸能力 并且借助于不仅调湿颗粒中固有的水分吸附/解吸能力以及调湿颗粒之间的空隙的水分吸附/解吸能力而具有优异的吸湿/解吸响应性。
