PROBLEM TO BE SOLVED: To obtain a moisture-donating carrier for deoxygenation agent of compact construction which weighs less and has high oxygen sbsorbing capacity by a method in which a specific ratio of a product whose starting material is fly ash and which has alkaline property and cation exchange function and a specific ratio of cement are included to form granulated materials having specific particle size. SOLUTION: A moisture donating carrier for use as a deoxygenation agent comprises 70-80 pts.wt. of product made from fly ash and having alkaline property and cation exchange function and 20-30 pts.wt. of cement, and the product is granulated material and sum of the product and cement does not exceed 100 pts.wt. and particle size of the material is in the range of 0.1-1.5mm. Or a granulated material comprises 70-80 pts.wt. of a product, which is prepared by applying an alkaline treatment to fly ash, and 20-30 pts.wt. of cement and sum of the product and cement does not exceed 100 pts.wt. and particle size of the material is in the range of 0.1-1.5mm. And deoxygenation agent is prepared from iron powder, oxidation accelerating material, filler, etc.
