Abstract
A positive electrode material consists of composite particles. Each of the composite particles includes a base material particle, a film, and a carbon nanotube. The film covers at least a part of a surface of the base material particle. The base material particle includes a positive electrode active material. The film includes a boron oxide. The carbon nanotube includes a first portion and a second portion. The first portion is buried in the film. The second portion is exposed on a surface of the film.
