To provide a super abrasive-grain grinding wheel using ceramic binder which exhibits stable grinding performance. A super abrasive-grain grinding wheel using ceramic binder is produced by bonding layers of super abrasive grains 13 containing super abrasive grains 10 bonded with ceramic binders (20, 30), wherein the layers of super abrasive grains 13 contain a first layer of super abrasive grains 11 which comprise super abrasive grains 10 bonded with ceramic binder 20 and a second layer of super abrasive grains 12 formed by aggregating clusters of super abrasive grains that are made by bonding the super abrasive grains with the ceramic binder 30. |
