PROBLEM TO BE SOLVED: To provide a laser cutting method and a laser cutting device in which unnecessary parts generated during laser cutting can be reliably removed.SOLUTION: A laser cutting method is characterized in that, after cutting an electrode tab 101 and a scrap 120 by irradiating an electrode foil with laser beams, a stage 11 is lifted on which a battery 100 having a heavier mass than the scrap 120 on the electrode tab 101 side is placed, and the scrap 120 is removed after the electrode tab 101 and the scrap 120 are moved in the direction orthogonal to a plane of the electrode foil. |
