The electrode sheet has a longitudinal direction and a lateral direction and constitutes an electrode of a secondary battery by being wound with the lateral direction as an axial direction. The electrode sheet includes a current collector that includes a resin layer, and a first current collecting layer and a second current collecting layer that are respectively provided on both surfaces of the resin layer; a first active material layer that is provided on a surface of the first current collecting layer on a side opposite to the resin layer; and a first metal sheet that is bonded to one end of the first current collecting layer in the lateral direction and has a first bonding mark formed along the longitudinal direction by the bonding, where the first metal sheet has a first extending part that extends from the first current collecting layer in the lateral direction.",
