The lithium-nickel composite oxide contains lithium (Li), nickel (Ni), and an element M (M), wherein, the element M is at least one element selected from Mn, V, Mg, Mo, Nb, Ti, Co, and Al, wherein, in the starting material, a ratio of number of tungsten atoms to a total number of nickel atom and the element M atoms contained in the lithium-nickel composite oxide is 0.05 at. % or more and 3.00 at. % or less.",
