Abstract

A positive electrode active material comprises a primary particle (1) and a covering (5). The primary particle includes lithium manganese phosphate. The covering (5) covers at least part of a surface of the primary particle (1). In a radial direction of the primary particle (1), the covering (5) includes a first region (5a) and a second region (5b). Each of the first region (5a) and the second region (5b) includes carbon. In TEM-EDS analysis, signal intensity of manganese in the second region (5b) is more than signal intensity of manganese in the first region (5a).
