PROBLEM TO BE SOLVED: To provide a method for producing a deodorant material capable of obtaining a deodorant material with suppressed emission of ammonia. SOLUTION: By adding an alkali to a mixture containing a hydrous magnesium silicate clay mineral and a compound of a Group 2 element of the periodic table, the pH is within the range of (pK2+0.2) to (pK2+1.7). An aqueous solution of an aliphatic aminocarboxylic acid (excluding a diamino compound) adjusted so that (the pK2 is a dissociation constant between a zwitterion and an anion of the aliphatic aminocarboxylic acid), A group aminocarboxylic acid is bonded to the metal ions on the outer surface and the inner surface of the pores by substitution with water of crystallization coordinated to the metal ions on the outer surface and the inner surface of the pores of the hydrous magnesium silicate clay mineral, In a molecular state that is not a crystal or a lump, it is uniformly and highly dispersed and supported, and at least a part of the compound of the Group 2 element of the periodic table is a metal ion of the Group 2 element of the periodic table [M2+ (M is Group 2 of the periodic table). The method for producing a deodorizing material is characterized in that the deodorizing material is present in a state of being formed.
