Claim:
1. A current collector for a bipolar lithium ion secondary battery, comprising: a first electrically conductive layer in which electrically conductive filler is added to a substrate containing imide group-containing resin; and a second electrically conductive layer that functions to isolate lithium ions, the second electrically conductive layer including an isolation resin layer and a metal layer, the isolation resin layer having a constitution in which electrically conductive filler is added to a substrate containing resin not containing imide group, and the first electrically conductive layer being located in a manner such that a positive electrode active material layer is closer thereto than the second electrically conductive layer, wherein the second electrically conductive layer further includes a metal elution-preventing layer, the metal elution-preventing layer being located on a surface of the metal layer to face the first electrically conductive layer.
