Abstract: The present application provides a current collector, electrode plate, cell, battery, device, manufacturing method, and apparatus. The current collector includes a conductive layer and a support layer, wherein the conducive layer is provided on a surface of the support layer, and the support layer includes an insulating base and a support structure embedded in the insulating base to enhance strength of the support layer, which not only increases an overall strength of the current collector and can improve the problem of tape breakage during processing, but also allows strength of the support layer to be close to strength of the conductive layer, narrowing the gap in structural strength between the support layer and the conductive layer, and reducing the difference in deformation between the conductive layer and the support layer during processing, so that it is conducive to improving processing performance of the current collector.
