PROBLEM TO BE SOLVED: To provide a method for cutting a glass substrate material, by which the glass substrate material is also cut while forming a marking line with "a scriber", the formation of chipping or the like is almost suppressed, and a cut surface having a good quality can be obtained. SOLUTION: The method for cutting the glass substrate material includes a removing process for removing a part or whole of the rear surface of the glass substrate material and a scribing process for forming the ruled line which causes a crack reaching the rear surface of the glass substrate material.
