PURPOSE: A dehumidifying agent, a dehumidifying element using the same, and a manufacturing method thereof are provided to stably absorb moisture regardless of change of relative humidity of the air without loss of salt liquid. CONSTITUTION: A manufacturing method of a dehumidifying agent includes a step for contacting hygroscopic salt with superabsorbent polymer and a step for drying hydrogel generated by contact of the superabsorbent polymer and the hygroscopic salt. The superabsorbent polymer includes a first component having electrostatic repulsive force and a second component having hydrophilic property. The first component comprises polyacrylic acid or polymethacrylic acid. The second component comprises polyacrylamide, polyvinyl alcohol, polyvinylamine, ethylene oxide, starch and cellulose. |
