Abstract
In this laser cutting method and laser cutting device with which a base material is cut by irradiating, with laser, a surface of a base material formed of a composite material, an irradiation step for swinging the laser in a tolerance direction crossing the length direction of a cutting line while moving the laser relative to the base material along the length direction of the cutting line for cutting the base material is repeatedly performed on the cutting line, thereby cutting the base material, and in the irradiation step, a swing width in the width direction of the laser is decreased as the depth in the depth direction from the surface of the base material toward the rear surface increases.
