PURPOSE:To obtain a sheet having an odor-adsorptive property and gas permeability, by stretching a sheet comprising a thermoplastic resin, an inorganic filler and an odor-adsorbing agent. CONSTITUTION:An odor-adsorptive sheet obtained by at least unidirectionally stretching a sheet comprising a thermoplastic resin, an inorganic filler and an odor-adsorbing agent. As the thermoplastic resin used, a polyolefin is particularly suitable. Examples of the odor-adsorpbing agents include active carbon, porous silica, porous alumina, porous silicaalumina metal salt and a metal salt/ascorbic acid mixture. When the sheet having gas permeability and an odor-adsorptive property is used, it is possible that when there is an odoriferous substance on one side of the sheet, no odor can be sensed on the other side in spite of its permeability. This sheet has one having an odor-adsorbing property and gas permeability and is useful for disposable sanitary products such as paper diapers and sanitary articles and medical products such as sheets for patients.
