RESIN CURRENT COLLECTOR AND LAMINATED TYPE RESIN CURRENT COLLECTOR, AND LITHIUM ION BATTERY COMPRISING THIS

To provide a resin current collector which exhibits liquid bleeding prevention property and low resistance, can suppress the generation of an oxidation current, and exhibits moldability that enables film thinning.A resin current collector containing a polyolefin resin and two kinds of conductive carbon fillers, a first conductive carbon filler (A1) and a second conductive carbon filler (A2), in which the first conductive carbon filler (A1) is graphite or carbon black, the second conductive carbon filler (A2) is a carbon nanotube or a carbon nanofiber having a specific surface area of 35 to 300 m2/g, a total surface area of the first conductive carbon filler (A1) contained in 1 g of the resin current collector is 0.5 to 9.0 m2, and a mass proportion of the first conductive carbon filler (A1) is 30% by mass or less with respect to a mass of the resin current collector.
