PROBLEM TO BE SOLVED: To provide a break method and a break device which can easily break along a scribe line by a low load with a simple mechanism without using a break bar.SOLUTION: By disposing a first projection formation unit 4, which comprises a projection 4a perpendicular to a substrate feed direction, on an intermediate undersurface of a belt 2 of a conveyor 3 for conveying a substrate M, and pushing up the belt 2, a portion of the belt 2 is projected, and a projection strip part 2a perpendicular to the substrate feed direction is formed. The substrate M is placed on the belt 2 in a state in which a scribe line S1 to be broken is perpendicular to the substrate feed direction. The substrate M is conveyed from an upstream side flat part 2b of the projection strip part 2a to a downstream side flat part 2c. By infiltrating a crack of the scribe line S1 formed on a bent outer surface side in a thickness direction by the bending of the substrate M when the substrate M is shifted to the downstream side flat part 2c beyond the projection strip part 2a, the substrate M is broken along the scribe line S1. |
