An electrode including a collector layer, an active material layer, and a bonding layer is disclosed. The collector layer is made of an electric conductor. The active material layer includes active material particles that stores charge, a conduction assistant that transports the charge stored in the active material particles to the collector layer, and a binder that binds the active material particles with the conduction assistant. The active material layer has a first surface relatively distal from the collector layer and a second surface opposing the first surface and relatively proximal to the collector layer. The projections and recesses are formed on the first surface side. The bonding layer bonds the collector layer and the active material layer. |
