Abstract: An electricity storage device includes an internal element that has a first main surface, a second main surface, a first side surface, a second side surface, a first end surface, and a second end surface, and that further includes a first internal electrode drawn out to the first end surface, a second internal electrode drawn out to the second end surface, a separator layer disposed between the first and second internal electrodes, and an electrolytic solution. Moreover, a first end surface electrode is disposed on the first end surface; and a second end surface electrode is disposed on the second end surface. The first internal electrode, the second internal electrode, the separator layer, the first end surface electrode, and the second end surface electrode are integrally sintered to form a sintered body.
