Abstract
According to an aspect of the present invention, there is provided a positive electrode material which contains a positive electrode active material, and a dielectric material having a perovskite crystal structure. In the positive electrode material, in an X-ray diffraction pattern (vertical axis: diffraction intensity, horizontal axis: diffraction angle 2θ (rad)) obtained by X-ray diffraction measurement using a CuKα ray, a highest intensity peak which is a peak derived from the dielectric material and has the highest intensity is in a range satisfying 2θ=31° to 32°, and a half width x of the highest intensity peak satisfies the following expression: 0.22≤x≤0.33.
