Zusammenfassung:	Provided is a positive electrode active material in which aluminum is dispersed uniformly. This positive electrode active material is characterized by being a crystalline oxide including lithium, nickel, and aluminum, wherein the dispersion of said aluminum in primary particles of the oxide is uniform. L'invention concerne un matériau actif d'électrode positive dans lequel de l'aluminium est dispersé uniformément. Ce matériau actif d'électrode positive est caractérisé en ce qu'il est un oxyde cristallin comprenant du lithium, du nickel et de l'aluminium, la dispersion dudit aluminium dans des particules primaires de l'oxyde étant uniforme. アルミニウムの分散が均一である正極活物質を提供する。　リチウム、ニッケル及びアルミニウムを含有する結晶性の酸化物であり、前記酸化物における一次粒子内のアルミニウムの分散が均一であることを特徴とする正極活物質。
