Abstract: A laser processing apparatus and a stack processing apparatus are provided. The laser processing apparatus can perform steps selectively by switching of optical paths. The steps are a step in which a first surface of a flat-plate structure is irradiated with a laser and a step in which a surface opposite to the first surface of the structure is irradiated with the laser. The laser is a linear laser whose shape on the irradiated surface is a rectangle. By laser irradiation performed while the structure is moved in the horizontal direction, the whole or a desired region of the first surface or the opposite surface of the structure can be processed.
