Abstract
An electrode is used for an electric storage device that includes plural electrodes that are stacked such that an ion-conductive layer is disposed between each pair of the electrodes. Each of the plural electrodes includes a current collector, and an electrode layer, formed on the current collector, which contains an active material. The configuration of the electrode layer (for example, the amount of the active material) varies according to the position in the electrode layer such that a current density in a first region of the electrode, where heat radiation performance is lower than the heat radiation performance in a second region of the electrode, is lower than the current density in the second region of the electrode.
