Abstract: 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.

Abstract: An inkjet printing head including: a common ink chamber having an outlet; and an individual ink flow path having a pressure chamber and leads ink from the outlet of the common ink chamber to a nozzle through the pressure chamber, wherein the common ink chamber and the individual ink flow path are formed of a plurality of thin plate members having holes formed thereon, the thin plate members being laminated and fixed onto one another by metal-metal junction, and wherein sectional area of the common ink chamber along a planar direction of the thin plate members is configured to be smaller at an end portion where the outlet is provided than at a central portion in a direction of thickness of the plurality of thin plate members.
