Abstract

A multilayer conductive film includes a layerincluding a conductive material containing a polymer materialhaving an alicyclic structure and conductive particlesand a layerincluding a material having durability against positive electrode potential. The multilayer conductive film has stability in an equilibrium potential environment in a negative electrode and stability in an equilibrium potential environment in a positive electrode, has low electric resistance per unit area in the thickness direction, and has excellent barrier properties for a solvent of an electrolytic solution. A battery including a current collector employing the multilayer conductive film can achieve both weight reduction and durability.
