<p>PROBLEM TO BE SOLVED: To provide a drying agent effectively dehumidifying moisture from the atmosphere and preventing from discharge of adsorbed moisture. SOLUTION: The drying agent is prepared by sealing a drying material of a dehumidifying component mixed with 40% ratio of a water-holding component to the dehumidifying component into a packing material provided with a film member of the material having moisture-permeable and water-proofing properties, a film member of the material of hard permeability, and/or a film member of the material having <1.6 (g/m2.24 hours) water vapor permeability.</p> |
