The dressing board 1 includes a flat dressing plate 30, a plurality of first grooves 31, and a second groove 32. The thickness TA of the flat dressing plate 30 is larger than the cutting depth when the cutting blade cuts the workpiece. The first groove 31 is formed to have the width H wider than the thickness of the cutting blade while leaving a thickness T1 smaller than the cutting depth from the surface 30a of the flat dressing plate 30. The second groove 32 is extended in the direction perpendicular to the first groove 31 on the back surface 30b of the flat dressing plate 30 and formed at a depth penetrating the first groove 31. |
