Abstract
The present invention provides a method by which it is possible to increase a processing speed in grinding processing using fixed abrasive particles, and to perform stable grinding processing. With the present invention, in grinding processing for grinding a main surface of a glass substrate (10), the glass substrate main surface is ground using a grinding tool that includes grinding abrasive particles, a bonding material for bonding the grinding abrasive particles, and dispersion particles that are harder than the bonding material and softer than the grinding abrasive particles, a ratio of an average particle diameter of the dispersion particles with respect to an average particle diameter of the grinding abrasive particles falling within the range of 0.8 to 1.2, the grinding abrasive particles being assembled abrasive particles (3) in which a plurality of grinding abrasive particles are bonded with a fixing material, the grinding abrasive particles and dispersion particles being dispersed and bonded in the bonding material.
