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. 【課題】ブレイクバーを用いず、簡単な機構で低荷重により容易にスクライブラインに沿ってブレイクすることができるブレイク方法並びにブレイク装置を提供する。【解決手段】基板Ｍを搬送するコンベア３のベルト２の中間下面に、基板送り方向に直交する凸部４ａを備えた第一凸部形成ユニット４を配置してベルト２を押し上げることにより、ベルト２の一部を隆起させて基板送り方向に直交する凸条部２ａを形成し、このベルト２に、分断すべきスクライブラインＳ１を基板送り方向に直交させた状態で基板Ｍを載置して、当該基板Ｍを凸条部２ａの上流側平坦部２ｂから下流側平坦部２ｃに搬送し、基板Ｍが凸条部２ａを乗り越えて下流側平坦部２ｃに移行する際の基板Ｍの屈曲によって、屈曲外面側に形成されているスクライブラインＳ１の亀裂を厚み方向に浸透させることにより、当該スクライブラインＳ１に沿って基板Ｍをブレイクする。【選択図】図２
