A main scribe line (MS) is formed along an intended divide line of a mother glass substrate (10) by sequentially forming vertical cracks (Vm) along the intended divide line. The vertical cracks (Vm) extend in the thickness direction of the mother glass (10). Next, a subsidiary scribe line (SS) is formed along the main scribe line (MS), with a certain space therefrom. Consequently, the mother glass substrate (10) is divided along the main scribe line (MS). With this method, a substrate can be efficiently divided without requiring any complicated apparatus or the like. |
