An apparatus for correcting a coil is provided to improve flatness of a corrected coil by adjusting an inclination of a change curve of the corrected coil from a plastic region to an elastic region. An apparatus for correcting a coil includes a coil(1), a correction roller(10), and a backup roller(20). The apparatus corrects flatness of a coil by passing the coil between the correction roller arranged in a zigzag on an upper and lower parts. A diameter of the correction roller and a gap distance of the correction roller are decreased according to a propagation direction of the coil. An upper/lower backup roller supporting the correction roller is coupled to an upper/lower part of the correction roller. The gap distance between the backup roller and the diameter of the backup roller are decreased according to the propagation direction of the coil.
