Abstract
A coating layer 5 made of a fluorine-containing polymer and having a thickness of 20 to 700 nm is formed on a surface of a nozzle forming member made of plastics which can be ablated by an excimer laser. Then, the nozzle forming member 1 is irradiated from its back by the excimer laser to generate high-density excited species in the irradiated portion. Using the force owing to the decomposition and scattering of the excited species, a nozzle 7 is formed and the coating layer 5 on the nozzle 7 is removed.
