Abstract
An all-solid lithium ion secondary battery has a pair of electrode layers and a solid electrolyte layer between the pair of electrode layers. In the all-solid lithium ion secondary battery, at least one electrode of the pair of electrodes has an active material layer and an intermediate layer on the surface of the active material layer on the side of the solid electrolyte layer, and each of the solid electrolyte layer, the intermediate layer, and the active material layer includes a compound containing Li and two or more shared types of metal elements other than Li, the two or more shared types of metal elements in the solid electrolyte layer, the intermediate layer, and the active material layer are identical between the solid electrolyte layer, the intermediate layer, and the active material layer.
