Abstract: PROBLEM TO BE SOLVED: To provide a grinding wheel capable of keeping high bite, high surface roughness and a high grinding rate over a long time and having a long grinding life. SOLUTION: This grinding wheel is characterized by being manufactured by using abrasive grains formed by covering their surfaces with a binding material, and having an uneven coverage for individual abrasive grains and an overall coverage of 85% or more for all the individual abrasive grains. When it is assumed that a coverage for the abrasive grains with the surfaces thereof completely covered with the binding material is 100%, that for those with the surfaces generally covered is 90%, that for those with the surfaces incompletely covered and with part of the surfaces thereof exposed is 50% and that for those with the surfaces almost non-covered is 0%, the grinding wheel is manufactured by using an abrasive coating wherein the abrasive grains having the different coverages coexist and the overall coverage for all the individual abrasive grains is 85% or more.  In the grinding wheel, the binding material for covering the abrasive grains belongs to a vitrified group or a resinoid group, and the maximum grain diameter of the binding material is 1/5 or less of the average diameter of the abrasive grains.
