description The present application discloses a composite current collector, an electrode, a secondary battery and an electric device. The composite current collector comprises a support layer and conductive layers; the support layer comprises a base layer and a conductor component, the base layer has two opposite surfaces in the thickness direction, and the conductor component is provided in the base layer and/or on the side wall of the base layer adjacent to the surfaces; the conductive layers are stacked on at least one surface of the base layer, and the conductive layers are electrically connected to the conductor component. According to the composite current collector, by additionally providing the conductor component in the support layer, the resistance of the support layer is effectively reduced and the resistance of the composite current collector is effectively reduced, so that the overheating phenomenon in the charging and discharging process of battery cells containing the composite current collector of the pr
