Abstract

There is provided an energy storage device having an insulating layer excellent in insulation properties. There is provided an energy storage device including an electrode assembly having a pair of electrodes overlapped with each other. At least one of the electrodes includes a current collecting substrate, an active material layer arranged on the current collecting substrate, an intermediate layer arranged between the current collecting substrate and the active material layer, and an insulating layer arranged on the current collecting substrate. The active material layer contains an active material and a first binder. The intermediate layer contains a carbonaceous material and a second binder. The insulating layer contains an insulating material and a third binder. The second binder is a nonaqueous binder. The third binder is an aqueous binder.
