製品コストが高くなるという問題点があった。Since the conventional spray plate 1 shown in FIGS. 8 and 9 is manufactured by press working, a large number of press dies are required, resulting in high preparation costs and high precision products. It is difficult to fabricate, and further there is a problem that it requires a burr removal finishing process after the pressing process, which is a difficult labor and is expensive. Since the conventional nozzle body 4 shown in FIGS. 10 to 13 is manufactured by cutting, it is extremely difficult to machine difficult-to-cut materials, and a great deal of labor is required for deburring and finishing.
There is a problem that the product cost becomes high.

得られる。The spray plate 7 is manufactured by etching. For example, according to the photo-etching method, after selectively covering and protecting the surface of the material to be processed (disk) using a photographic master and a photoresist, the uncovered portion is removed by etching, so that As shown in FIG.
A product having grooves 9 and 10 on both surfaces 7a and 7b is obtained.
