[Problem] To provide a conveyor and a conveying method that can correct creases in a supply roll to improve processing accuracy. [Solution] A conveyor (100) comprising: a supply roll (110) on which a belt-shaped cell material (W) is wound, the cell material being the material for an electrode or a separator; a corrective roller (340) for holding the cell material (W), which is fed out from the supply roll (110), in a conveyable manner while bending one surface of the cell material (W) that lies against the outer peripheral side of the supply roll (110) into a concave shape; and another roller for conveyably holding the cell material (W) while bending the other side of the cell material, which is different from the one side, into a concave shape; the radius of curvature of the surface of the corrective roller (340) that is in contact with the cell material (W) being less than the radius of curvature of the surface of the other roller that is in contact with the cell material (W). |
