The present invention addresses the problem of performing correction so that an axis line of a chuck and a core of a workpiece are highly accurately aligned with each other. Provided is a chuck correction method that is provided with a correction step. The chuck is provided with a body, a plunger, and a jaw. The body has a rear body and a front body that is disposed on the front side of the rear body, the plunger is provided in the body, and is configured so as to move on an axis line of the body, and the jaw is configured so as to move, due to the movement of the plunger, in the diameter direction with the axis line at the center by being guided by the front body. In the correction step, when a workpiece is held by the jaw, the front body is moved in the diameter direction with the axis line at the center, while maintaining the position of the rear body with respect to the axis line, or the front body is tilted with respect to the axis line, while maintaining the position of the rearbody with respect to the axis line.
