Abstract: A current collector, an electrode sheet, and a fabrication method for a current collector are disclosed. The current collector includes a support layer, a first electrically conductive layer and a second electrically conductive layer. The support layer has a first surface and a second surface arranged opposite to each other. The first electrically conductive layer has a grid structure distributed on the first surface and/or the second surface of the support layer. The second electrically conductive layer is provided on a surface of the first electrically conductive layer away from the support layer.
