Abstract

The positive electrode active material disclosed herein includes a base portion including a lithium transition metal complex oxide having a layered crystal structure, and a coating portion including an electroconductive oxide having a layered crystal structure. A smaller angle θ formed by a stacking plane direction of the lithium transition metal complex oxide and a stacking plane direction of the electroconductive oxide satisfies the following conditions: an average angle θave. obtained by arithmetically averaging the angle θ satisfies 0°≤θave.≤60°; and a ratio of points in which the angle θ is greater than 60° is 39% or less.
