Objective: To provide a mesh made out of an unlimited number of materials, and in particular which is made out of a material which has superior resistance to corrosion and chemicals yet is safe for humans, and to provide a mesh comprising holes whose shape and cross-sectional contour can be selected as needed. Configuration: An excimer laser beam L projected by laser oscillator 12 is shaped by being directed through a number of openings 2 in mask 1. The shaped beams pass through an optical system containing object lens 3 and are projected onto material 5, a thin piece of a polymer such as polysulf- one or polyester, which is fixed on work stage 4. The image of the pattern formed by openings 2 is made to appear, and a number of holes 6 are created in material 5 to produce a thin mesh 7 suitable for use in an inhaler or a similar device. 34
