An electrode and a battery including the electrode, including an insulating member disposed from an active material layer on a current collector of the electrode to an exposed portion, can reduce nonuniformity in pressure applied to the electrode irrespective of the thickness of the insulating member and can reduce nonuniformity in an electrode reaction. The electrode includes a current collector; an active material layer that is stacked on the current collector so as to form an inclined portion while leaving an exposed portion at which a part of the current collector is exposed, the inclined portion being inclined in such a way that a thickness thereof decreases toward the exposed portion; and an insulating member that covers a region from the exposed portion to the inclined portion. |
