PROBLEM TO BE SOLVED: To provide a grinding method and a grinder of a slab capable of precisely recognizing a shape of the slab and providing a favorable grinding surface state even on the slab diagonally arranged on a carrier passage with respect to the carrying direction or slab edges of both sides in the cross direction which is not rectilinear. SOLUTION: This grinding method has a process to pick up an image of the slab 17 carried in the X direction from above and to measure its shape, a process to measure a distance to both side surfaces in the cross direction of the slab 17 along its overall length by using a pair of distance measuring means arranged at prescribed distance positions, a process to detect an abnormal value included in data of the distance measured by the distance measuring means and to correct it by using data of the shape of the slab 17, and a process to carry out the chamfering work of the edge by controlling a grinding wheel free to move in the X direction and in the Y direction orthogonal with the X direction by using the corrected data of the distance.
