Abstract: A plate includes a current collector, an intermediate layer layered on the current collector, and an active material layer layered on the intermediate layer. The intermediate layer contains conductive particles and insulating particles. At least a portion of an end edge of the intermediate layer is not covered with the active material layer. The intermediate layer hays a higher mass content of the insulating particles in a region not covered with the active material layer than that in a region covered with the active material layer.
