Abstract: A cathode includes a mixture of a cathode active material, a solid electrolyte, and a conductive material. The conductive material includes carbon black having an average particle size of less than or equal to 100 nm. When a cross-section of the cathode is observed using a scanning electron microscope, an area in which the carbon black is concentrated is found between the cathode active material and the solid electrolyte.
