Zusammenfassung:A manufacturing method of laser processed parts in which at least a pressure-sensitive adhesive layer is provided on a base material as a pressure-sensitive adhesive sheet for laser processing, using a material having specified physical properties. This method comprises adhering the pressure-sensitive adhesive sheet for laser processing to the laser beam exit side of the work by way of the pressure-sensitive adhesive layer, processing the work by irradiating the work with a laser beam of within 2 times of the irradiation intensity for forming a through-hole in the work, at higher than the irradiation intensity of threshold for inducing ablation of the work, and peeling the pressure-sensitive adhesive sheet for laser processing from the work after the machining. Therefore, contamination of the work surface by decomposition products can be effectively suppressed, and laser processed parts can be manufactured easily and at high production efficiency.
