Abstract: An aspect of the present invention is an electrode which includes an active material layer, and an insulating layer layered on a surface of the active material layer, in which the insulating layer contains a filler and a first binder, and a content of the first binder in the insulating layer is 8% by mass or more. Another aspect of the present invention is an electrode which includes an active material layer, and an insulating layer layered on a surface of the active material layer, in which the insulating layer is a dry coating product containing a filler and a binder. Still another aspect of the present invention is a method for manufacturing an electrode, which includes the steps of forming an active material layer, and laminating an insulator containing a filler and a binder on a surface of the active material layer to form an insulating layer, in which the insulator does not contain a solvent.

Abstract: In an electrode having a covering layer stacked on a composite layer, an increase in resistance of the electrode is suppressed. An electrode plate includes a composite layer including active material particles and a covering layer including filler particles stacked on the composite layer. In this electrode plate, a particle size (D30) of the active material particle is set to be equal to or smaller than a particle size (D50) of the filler particle.
