| description | To provide a method for producing an oxo-acid metal salt having high degree of freedom in material design and excellent mass productivity.SOLUTION: A method for producing an oxo-acid metal salt includes a step of making an oxo-acid salt react with an alkali-free metal salt in a solvent containing water and/or alcohol to obtain a precipitate, and recovering the obtained precipitate by solid-liquid separation, and a step of heat-treating the recovered precipitate at a temperature of 50°C or higher and 1600°C or lower to obtain a heat-treated product. The oxo-acid salt is either one or both of an oxo-acid alkali metal salt and an oxo-acid ammonium salt. The metal element contained in the alkali-free metal salt is at least one kind selected from the group consisting of a typical element, a transition element, and a rare earth element. The final pKa of the conjugate acid of the anion of the alkali-free metal salt is 7.0 or less. The reaction is carried out at a temperature of 0°C or higher and less than 100°C under a pressure of 0.8 atm or more and 1.2 atm or less.SELECTED DRAWING: Figure 1
