Zusammenfassung:PROBLEM TO BE SOLVED: To provide a lithium-transition metal-based compound powder which makes it possible to provide a lithium secondary battery which has a high initial efficiency and a good rate characteristic when used as a lithium secondary battery positive electrode material.SOLUTION: The lithium-transition metal-based compound powder for lithium secondary battery positive electrode material comprises an oxide expressed by the general formula (1). The powder has Li holes and oxygen holes in a crystal structure, and a root mean square (RMS) of surface roughnesses of primary particles of the powder is 1.5 nm or less, which conforms to JIS B 0601:2001. xLiMO(1-x)LiNO(1), where x meets 0
