Abstract
A humidity-conditioning sheetexcellent 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 layerformed by bonding together, with a thermoplastic resin powder, humidity-conditioning particleswhich reversibly adsorb and desorb water vapor. The void ratio of the humidity-conditioning layeris 5% or more. Since a ratio of voidsformed between the humidity-conditioning particlesis high, the voidsbetween the humidity-conditioning particlescan 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.
