Zusammenfassung:	PURPOSE:To improve the durability of a zeolite catalyst supporting copper and an alkali earth metal. CONSTITUTION:A catalyst for cleaning a waste gas is produced in such a way that copper ion, at least one kind of metal ions of alkali earth metal and alkali metal and chlorine ion are supported on a zeolite, dried and burned. At that time, a molar ratio of SiO2/Al2O3 is controlled to be 10-200 in the zeolite.
