Abstract
One of the objects of the present invention is to provide an electrode having an active material layer and an insulating layer formed on a current collector in which the insulating layer has sufficient adhesion and which can be manufactured without significantly changing the manufacturing process. The electrode comprises a current collector, an active material layerformed on at least one surface of the current collector, and an insulating layerformed on the surface of the active material layer. The active material layerincludes an active material and a first binder. The insulating layerincludes non-conductive particles and a second binder. An interfacial binder ratio, which is a ratio of amount of a binder existing in an interface region between the active material layerand the insulating layerper unit thickness of the interface region to amount of a binder existing in the active material layerper unit thickness of the active material layer, is 85% or more.
