PROBLEM TO BE SOLVED: To provide a method for purifying an aqueous solution of an amide compound capable of obtaining the aqueous solution of the amide compound containing less impurity and having less foaming property, and a method for producing the amide compound. SOLUTION: The method for purifying the amide compound is provided by filtering the aqueous solution containing the amide compound obtained by effecting a living body catalyst to a nitrile compound by using an ultrafilter membrane having a fractionizing molecular weight of≥1,000 and <10,000.
