The present invention provides an electrode composition containing an inorganic solid electrolyte, an active material, and distributed components bound to the inorganic solid electrolyte and the active material. One type of the distributed components is a binder. A polymer forming this binder contains a repeating unit having an amino group, a sulfanyl group, a hydroxy group, a carboxy group, or an anone group. In an electrode active material layer formed of the electrode composition, the distribution ratio of the distributed components with respect to the inorganic solid electrolyte exceeds 60%. The present invention also provides an electrode sheet for an all-solid-state secondary battery and an all-solid-state secondary battery using this electrode composition, as well as methods for manufacturing the electrode composition, the electrode sheet for an all-solid-state secondary battery, and the all-solid-state secondary battery. |
