To provide an electrode for a lithium ion secondary battery capable of enhancing a charge and discharge cycle durability of an electrode that uses a resin current collector. An electrode for a lithium ion secondary battery provided with a resin current collector including a polyolefin resin matrix and a conductive filler A, and an electrode active material layer provided on the resin current collector, in which a crosslinked resin thin-film layer, which contains an Ni filler as a conductive filler B that does not alloy with Li and which has impermeability to the electrolyte solution, is arranged between the resin current collector and a negative electrode active material layer.
