Abstract:
1. An electrical storage device, comprising: a solid electrolyte layer; and electrode assemblies stacked with the solid electrolyte layer interposed therebetween, each electrode assembly including a current collector on which a plurality of electrode parts are provided, wherein a part of the solid electrolyte layer is located between successive electrode parts in a direction perpendicular to the stacking direction on at least one of successive electrode assemblies in the stacking direction, and wherein, in each of the electrode assemblies, a formation density of the electrode parts in a first region that is closer to the center in each of the electrode assemblies is lower than a formation density of the electrode parts in a second region on the side of a periphery in each of the electrode assemblies from the first region.
