To provide an inexpensive, safe electrolyte aqueous solution absorbent wide in application and good in handleability in its transport or preservation, and to provide a method for producing the same.

This electrolyte aqueous solution absorbent is characterized by comprising an electrolyte aqueous solution-absorbing polymer consisting of a water-insoluble polymer with hydrophilic polar groups introduced thereinto and a sucking material. The other objective method for producing the above electrolyte aqueous solution absorbent is characterized by comprising packing a water-permeable bag-shaped body with the above-mentioned electrolyte aqueous solution-absorbing polymer and sucking material.
