A compound oxide powder producing method for producing compound oxide powder made of at least two kinds of metals. A solution 2, in which a first metal compound for producing, when hydrolyzed, a hydroxide or oxide is dissolved in an organic solvent, and an emulsion 1, which contains another metal in the form of ions in an aqueous phase inside of the inverse micelles formed by an surfactant in an organic solvent, are individually mixed in flowing states. The mixed liquid is stirred while being continuously caused to flow to the downstream side of a mixing portion 8 of the first solution and the emulsion. Primary particles are formed by the hydrolysis of said first metal compound inside or in the interface of said inverse micelles whereas secondary particles are formed by the agglomeration of the primary particles.
