Provided is a lithium metal composite oxide (powder) having a layered structure, which is capable of exhibiting excellent characteristics in both charge-discharge cycle ability and initial charging and discharging efficiency, and is capable of effectively reducing initial resistance, when being used in a positive electrode of a lithium battery. The lithium metal composite oxide (powder) comprises an amount of S which is less than 0.10% by mass of the lithium metal composite oxide powder, a ratio of a crystallite size of a (003) plane to a crystallite size of a (110) plane which is equal to or greater than 1.0 and less than 2.5, and a ratio of a primary particle area to a secondary particle area of 0.004 to 0.035. |
