An electrode plate for power storage devices having a high capacity and a power storage device including the electrode plate for power storage devices, an exemplary embodiment includes a strip-shaped positive electrode core and a positive electrode active material layer provided on at least one surface of the positive electrode core. A bare part is formed in an end portion of the positive electrode core in the width direction. The bare part is a part in which the surface of the core is exposed and to which a positive electrode lead is to be connected. The positive electrode active material layer has a thin part in at least part of a first region aligned with the bare part in the longitudinal direction of the positive electrode core. The thin part is thinner than a second region, which is a region other than the first region.
