A straightening device for welding wire (1) is provided with two sets of roll groups (13a), (13b) having a plurality of straightening rolls (12) with which bends in a welding wire (W) are straightened by passing the welding wire (W) through the two sets of roll groups (13a), (13b). The plurality of straightening rolls (12) configuring the roll groups (13a), (13b) are arranged at a predetermined arrangement interval along a passing direction of the welding wire (W) in such a way as to face with each other across a straightening path (T) along which the welding wire (W) passes, and the two sets of roll groups (13a), (13b) are arranged so that the directions in which they face across the straightening path (T) are different from each other. By configuring the straightening rolls (12) by small-diameter rollers, adverse effects on the welding wire (W) are suppressed, and the welding wire (W) is straightened finely. |
