Provided is a breaking apparatus capable of reducing time needed for a break of a brittle material substrate, comprising: a table (2) for putting the substrate; a beam arranged parallel to a mounting surface in the upper part of the table (2); a guide shaft (8) formed on a appropriate beam (7) along the polishing direction of the beam (7); and multiple break bars (10) movably formed along the guide shaft (8), wherein the break bars (10) are formed to be able to elevate through a elevating shaft (12), and the table (2) is rotatably formed with a shaft perpendicular to the mounting surface as a center, and accordingly, the multiple break bars (10) are formed to be a series posture arranged in serious along the polishing direction of the beam (7) and a separation posture to be in parallel along the direction perpendicular to the polishing direction of the beam (7). |
