PROBLEM TO BE SOLVED: To uniformize the particle diameter composition when a multiple oxide powder is produced by a ME method. SOLUTION: In the method for producing the multiple oxide powder comprising two or more kinds of metals, a solution 2 obtained by dissolving a first metal compound capable of forming a hydroxide or an oxide by hydrolysis into an organic solvent and an emulsion 1 containing other metal in a form of ion in a water phase at the inside of each reversed micelle formed by a surfactant in an organic solvent are mixed under such a state that the solution 2 and the emulsion are each allowed to flow, and then the forming of primary particles of the first metal compound at the inside or on the surface of the reversed micelle and the forming of secondary particles by the aggregation of the primary particles are performed by agitating the mixture while continuously allowing the mixture to flow to the down stream side of the mixing section 8 of the first solution and the emulsion.
