Abstract
An all-solid lithium ion secondary battery includes a pair of electrodes and a solid electrolyte provided between the pair of electrodes. At least one of the pair of electrodes includes an active-material layer and an intermediate layer. An active material constituting the active-material layer has a core-shell structure which has a core region and a shell region and a composition of the intermediate layer is intermediate between the solid electrolyte and the shell region.
