Zusammenfassung:	PROBLEM TO BE SOLVED: To efficiently decompose a compound containing a halogen by using calcium oxide or magnesium oxide which is prepared by containing at least one kind of a compound to be selected from an alkali metal chloride, alkali metal fluoride or the like and burning it in a nitrogen atmosphere. SOLUTION: When a treating agent for making harmless is manufactured by decomposing efficiently an organic halogen compound or the like at a high decomposing rate, calcium carbonate or calcium hydroxide or the like is used as a raw material. Then, one kind of a compound to be selected from sodium chloride, potassium chloride, potassium fluoride, lithium fluoride or the like is added within a range of 0.01 to 10 wt.% to the raw material, and burnt in a nitrogen atmosphere to manufacture the product. In using, at least one kind of such halogenating gas treating agents is filled in an excluding apparatus, and brought in contact with a halogenating gas at 200 to 900 deg.C. Thereby, operation can be executed for a long period of time, and can be continuously treated regardless of a concentration of the halogen compound in the gas.
