PRODUCTION METHOD OF INK-JET HEAD, AND INK-JET HEAD

摘要

PROBLEM TO BE SOLVED: To produce an ink-jet head part with high density and high accuracy. SOLUTION: A synchrotron radiation light(SR) 108 is directed to a conductive substrate 104 coated with a resist 101 to execute lithography. By nickel electrocasting, a nickel layer 110 is formed. Thereafter, the substrate and the resist are eliminated, so that a mold 111 is obtained. With the mold used, a hot embossing process is executed for forming a resin structure on the conductive substrate. Furthermore, a nickel layer is formed by electrocasting so as to obtain a metal part.
