The component which is produced with micro electrolytic plated method

摘要

(57) Abstract The component (23) of this invention has featured the plural membrane layers (32,33) which consecutively were formed to the top and bottom by micro electrolysis plating type metal precipitation or that it consists of plural functional plane surfaces. Furthermore at least inside one functional plane surface of the plural functional plane surfaces which form the outer part restriction aspect of the said component (23), the appraisal possibility one cord/code sign (60) is provided optically at least from outside it is formed during electrolysis plating processing. In order the particular component is suited as the perforated disk which is used for the especially injection valve, in addition to use for the ink jet printer, it is suitable because of gushing geyser entrance of the liquid, or because of spraying of the medicine.
