The invention discloses a composite current collector for a corrosion resistance and high conductivity pseudocapacitance type supercapacitor and a preparing method of the composite current collector. The composite current collector comprises a base material, one face or the two faces of the base material is/are coated with a conductive bonding transition layer/conductive bonding transition layers, and a conductive corrosion resistance layer/conductive corrosion resistance layers is/are bonded to the conductive bonding transition layer/conductive bonding transition layers. The composite current collector is resistant to corrosion, high in conductivity, simple in production process, continuous and efficient in production and each to produce in a mass mode.
