A power storage device that includes an electrolyte retaining layer between a first internal electrode and a second internal electrode. The electrolyte retaining layer retains an electrolyte. The first internal electrode has a first current collector and a first active material layer. The first active material layer is on a surface of the first current collector, which is closer to the second internal electrode. The second internal electrode has a second current collector and a second active material layer. The second active material layer is on a surface of the second current collector, which is closer to the first internal electrode. At least one of the electrolyte retaining layer, first active material layer, and second active material layer is exposed at the first and second end surfaces of the power storage device. |
