Abstract

PURPOSE: To manufacture a titled plate precluding a damage of filtering material by preventing a formation of burr, by forming a thin metallic plate having prescribed photoresist film provided with many apertures etc. around a central aperature and performing a etching treatment etc. for said plate.
CONSTITUTION: A photoresist film having a prescribed pattern is provided onto the surface of a sensitive film formed previously on a metallic thin plate 11. Many units are arranged, each of which is constituted of an aperature 17 at the center, a circular plate part 12 provided with many apertures around the aperture 17, a dissolving part 13 around the plate part 12, a remained part 14 around the part 13; recessed parts 15 are provided to a part of the outer circumference of the part 12, and connecting parts 16 are provided between the recsses 15 and the part 14. The apertures 17, 18 and the annular recess 13 are etched respectively to form air spaces, and the parts 15 are cut off at their roots, thus the titled plate is formed. As burrs to be cut are formed at the bottom of the recesses 15, the filtering material is not damaged even when a thin plate of fluororesin is coated as a filtering material.
