Summary:PROBLEM TO BE SOLVED: To provide a double metal cyanide complex catalyst (hereinafter, represented as DMC catalyst) which has a high catalytic activity and a producing method for stably producing the same. SOLUTION: In this producing method of DMC catalyst, an organic ligand is coordinated on a reaction product obtained by reacting halogenated metallic salt with cyanized transition-metallic compound. Therein, an organic solvent which does not substantially contain water is used as the reaction solvent of halogenated metallic salt and cyanized transition-metallic compound as raw material.
