Provided is a breaking method by which an end surface strength can be stronger. A method for breaking a brittle material substrate comprises a step for forming a scribe line on the brittle material substrate, and a breaking step for breaking along the scribe line. In the breaking step, a break roller is pressed on and applies a load to the brittle material substrate placed on a table by rolling the break roller near the scribe line along a position separate from the scribe line to one side, so as to fold at a low load and divide the substrate. |
