Summary:PROBLEM TO BE SOLVED: To provide the manufacturing method of a lithium transition metal composite oxide having high filling property and high charge discharge characteristics useful for a positive active material of a lithium battery. SOLUTION: The manufacturing method of the lithium transition metal composite oxide is that a lithium transition metal composite oxide precursor changing to the lithium transition metal composite oxide by heat treatment is primarily heat treated in the oxidizing atmosphere, and then secondarily heat treated under the existence of carbonate compounds in the non-oxidizing atmosphere.
