<P>PROBLEM TO BE SOLVED: To provide a method for measuring the content of metal ions in a sample capable of simply and precisely measuring the content of the metal ions in the sample containing zeolite ion-exchanged with metal ions. Ž<P>SOLUTION: The method for measuring the content of the metal ions in the sample is a method for measuring the content of the metal ions in the sample ion-exchanged with the metal ions and has the step of mixing a flux with the sample, the step of heating and melting the mixture obtained by mixing the flux with the sample, the step of adding a non-oxidizing acid to the hot melt obtained by heating and melting, and the step of measuring the content of the metal ions in the hot melt to which the non-oxidizing acid is added.
