PROBLEM TO BE SOLVED: To reliably remove a distortion originally existing and a distortion produced during a grinding work, when grinding a plate-shaped object. SOLUTION: In this device for grinding a plate-shaped object, a supporting means 20 comprising a rotatable supporting table 21 to support the supporting surface of the plate-shaped object and a side supporting member 22 to support the side of the plate-shaped object are mounted, and the plate-shaped object can be supported by the side supporting member 22 without tightly fixing the plate-shaped object. In addition, in this method for grinding the plate-shaped object, the plate-shaped object is supported by the side supporting member 22 by using the plate-shaped object grinding device without tightly fixing the plate-shaped object, a grinding stone rotating while rotating the supporting table 21 is brought into contact with the surface of the plate-shaped object to be ground, and the plate-shaped object is ground so as to have a designated thickness.
