    摘要: An electrode for all-solid-state secondary batteries which enables the achievement of a practicable all-solid-state secondary battery even if an electrode active material layer does not contain a solid electrolyte which has been an essential ingredient for conventional electrodes for all-solid-state secondary batteries; and a practicable all-solid-state secondary battery which uses an electrode in which an electrode active material layer does not contain a solid electrolyte. The all-solid-state secondary battery includes a positive electrode, a solid electrolyte layer and a negative electrode, the positive electrode and/or the negative electrode has an electrode active material layer on a collector, the electrode active material layer contains an electrode active material and a binder resin; the binder resin contains a polyimide resin; and the electrode active material layer does not contain a solid electrolyte, while containing a lithium salt that has a solubility of 0.1 g or more per 100 g of a solvent at 25° C. with respect to water or at least one organic solvent.
