A dressing member for use in dressing grinding stones contains spherical abrasive grits, and a binder fixing the abrasive grits. Preferably, the abrasive grits may be silica grits, and the abrasive grits may have a ratio of minor axis to major axis of 0.7 or greater. Also preferably, the abrasive grits may be contained at a content of 20 wt % or higher but 80 wt % or lower. Also preferably, the abrasive grits may have an average grit size of 0.1 μm or greater but 3.5 μm or smaller. Also preferably, the binder may be a vitrified bond or a resin bond.

What is claimed is: 
     
         1 . A dressing member for use in dressing grinding stones, comprising:
 spherical abrasive grits; and   a binder fixing the abrasive grits.   
     
     
         2 . The dressing member according to  claim 1 , wherein
 the abrasive grits are silica grits, and   the abrasive grits have a ratio of minor axis to major axis of 0.7 or greater.   
     
     
         3 . The dressing member according to  claim 1 , wherein the abrasive grits are contained at a content of 20 wt % or higher but 80 wt % or lower. 
     
     
         4 . The dressing member according to  claim 1 , wherein the abrasive grits have an average grit size of 0.1 μm or greater but 3.5 μm or smaller. 
     
     
         5 . The dressing member according to  claim 1 , wherein the binder is a vitrified bond or a resin bond.
