摘要： A method of manufacturing an ink jet printing head includes: forming a first laminated structure by laminating at least two metal plates having a hole formed thereon and fixing the metal plates to one another by metal-metal junction, and by laminating a plurality of thin plate members having a hole formed thereon, the thin plate members including the metal plates, and fixing the thin plate members to one another; forming a second laminated structure that includes at least a part of a common ink chamber, by laminating a plurality of thin plate members having a hole formed thereon and fixing the thin plate members to one another; and fixing the first laminated structure and the second laminated structure to each other while laminating the first laminated structure and the second laminated structure on each other.

摘要： A nozzle plate has a repellent film formed on or over a nozzle sheet. The repellent film is made by adding an emulsion polymer ultraviolet ray absorbent agent to a fluorine-based polymer. In this nozzle plate, an out-of-roundness of a nozzle formed on the repellent film side of the nozzle plate is smaller, so that variations in the propulsion direction of the ejected ink drops are reduce. Particularly, when the weight percentage of the emulsion polymer ultraviolet ray absorbent agent exceeds 20%, the shape of the nozzle hole formed on the water and oil repellent film side of the nozzle plate has a roundness of 2 .mu.m or less. Accordingly, few variations in the propulsion direction of the ejected ink drops occur, providing superior print quality.
