Abstract

See full text

The purpose of the present invention is to provide a grinding material which has a superior grinding rate and planarizing accuracy, with the grinding rate being less likely to be reduced over a relatively long period of time. The present invention is directed to a grinding material including a base, a grinding layer overlaid on a front face side of the base and including grinding grains and a binder for the grinding grains, and an adhesion layer overlaid on a back face side of the base, in which the grinding grains are diamond grinding grains, a wear quantity of the grinding layer as determined by a Taber abrasion test is no less than 0.03 g and no greater than 0.18 g, and, an Asker D hardness measured from a front face side of the grinding layer is no less than 80° and no greater than 98°.
