PROBLEM TO BE SOLVED: To provide a production method that can obtain a high-quality amine oxide which contains less residual unreacted aliphatic tertiary amine and hydrogen peroxide, hardly contains trace metals and is very stable in color, odor and so on during its storage. SOLUTION: This is a method for producing an amine oxide by reacting an aliphatic tertiary amine represented by formula (I) with hydrogen oxide. In this case, characteristically, a chelating agent is added after the aliphatic tertiary amine is reacted with hydrogen oxide. In formula (I), R<1> is an 8-36C hydrocarbon group, R<2> and R<3> are each a 1-4C alkyl or hydroxyalkyl group, AO is a 2-4C oxyalkylene group and n, an average mole number, satisfies the equation 0<=n<=11.
