Abstract
An active material, a solid electrolyte, and a solvent are hard-kneaded to prepare a first electrode material. A dispersion promotion component is added to the first electrode material to prepare a second electrode material. Slurry containing the second electrode material is prepared. An electrode is produced by applying the slurry to a surface of a base material. A composite body is formed by the solid electrolyte adhering to a surface of the active material. The dispersion promotion component promotes dispersion of the solid electrolyte in the solvent.
