PURPOSE:To prepare a drying agent which can be prevented from getting liquefied even with a small quantity of a water retention agent used combinedly by blending a polyacrylamide group high-molecular compound with deliquescent inorganic salt group. CONSTITUTION:A drying agent is prepared by blending polyacrylamide group synthetic high-molecular compound with deliquescent inorganic salt group such as calcium chloride or the like by means of a powder and grain mixer or by putting weight portions of two components in a packaging container and vibrating the same for blending. As the time of using said drying agent, the same can be put in a container as it is and used or enlosed in an envelope constituted of a breathing non-woven cloth or a permeable film. Even a small quantity of said drying agent is more effective than the water retention agents heretofore available, and deliquescent liquid generated by the moisture absorption of deliquescent inorganic salt can be retained perfectly by using the polyacrylamide group synthetic high-molecular compound.
