PURPOSE:A sheetlike zeolite complex, obtained by applying a compound of a polyurethane urea resin solution with zeolite to a base material, substrate, wet treating the substrate and activating the resultant porous sheet and having improved drying agent characteristic and heat resistance. CONSTITUTION:A sheetlike zeolite complex obtained by preparing a polyurethane urea resin solution from an organic diisocyanate, preferably 4,4'- diphenylmethane diisocyanate and a high polymer diol, preferably polyester diol and an amine based chain extender, preferably 4,4'-diaminodiphenylmethane, incorporating a toner and zeolite, preferably powdery synthetic zeolite or, as necessary, a solvent, mixing and stirring the mixture, applying and/or impregnating the resultant compound into a substrate, wet treating the substrate to produce a porous sheet and activating the resultant sheet while heating or evacuating.
