A breaking apparatus breaking, for separation of an object to be broken having one main surface having a preformed scribe line, said object to be broken from a side of the other main surface along said scribe line, the breaking apparatus comprising: a support (2, 2A, 2B) on which said object to be broken is fixedly mounted; a breaking bar located above said support, and having an edge at a lower end; a lift mechanism raising and lowering said breaking bar; and a controller controlling operation of each component of said apparatus, wherein said lift mechanism includes: a motor rotating in a horizontal plane; and an operation conversion mechanism (5,7,8) converting rotational operation of said motor to raising and lowering operation of said breaking bar, said controller includes: a motor controller controlling operation of said motor; characterised in that the controller includes; a torque sensing part sensing torque acting on said motor; and a breaking processing part controlling operation of each component of said apparatus to cause said apparatus to break said object to be broken, and in a state of said object to be broken being fixedly mounted on said support (2, 2A, 2B) with said one main surface being in contact with said support, said breaking processing part causes said motor controller to rotate said motor to thereby operate said operation conversion mechanism (5, 7, 8) so that said breaking bar is lowered toward a position on said the other main surface of said object to be broken corresponding to a position of formation of said scribe line, and determines that breaking of said object to be broken is complete based on a change in said torque sensed by said torque sensing part when said breaking bar is being lowered. a support (2, 2A, 2B) on which said object to be broken is fixedly mounted; a breaking bar located above said support, and having an edge at a lower end; a lift mechanism raising and lowering said breaking bar; and a controller controlling operation of each component of said apparatus, wherein said lift mechanism includes: a motor rotating in a horizontal plane; and an operation conversion mechanism (5,7,8) converting rotational operation of said motor to raising and lowering operation of said breaking bar, said controller includes: a motor controller controlling operation of said motor; characterised in that the controller includes; a torque sensing part sensing torque acting on said motor; and a breaking processing part controlling operation of each component of said apparatus to cause said apparatus to break said object to be broken, and a motor rotating in a horizontal plane; and an operation conversion mechanism (5,7,8) converting rotational operation of said motor to raising and lowering operation of said breaking bar, said controller includes: a motor controller controlling operation of said motor; characterised in that the controller includes; a torque sensing part sensing torque acting on said motor; and a breaking processing part controlling operation of each component of said apparatus to cause said apparatus to break said object to be broken, and a motor controller controlling operation of said motor; characterised in that the controller includes; a torque sensing part sensing torque acting on said motor; and a breaking processing part controlling operation of each component of said apparatus to cause said apparatus to break said object to be broken, and in a state of said object to be broken being fixedly mounted on said support (2, 2A, 2B) with said one main surface being in contact with said support, said breaking processing part causes said motor controller to rotate said motor to thereby operate said operation conversion mechanism (5, 7, 8) so that said breaking bar is lowered toward a position on said the other main surface of said object to be broken corresponding to a position of formation of said scribe line, and determines that breaking of said object to be broken is complete based on a change in said torque sensed by said torque sensing part when said breaking bar is being lowered.
