Abstract:
A manufacturing method for manufacturing an ink jet recording head including a plurality of ink ejection outlets arranged in an array; a first member having a plurality of grooves in fluid communication with said ejection outlets, respectively; a second member having a plurality of energy generating elements for producing energy for ejecting ink in said grooves through said ejection outlets; and a clamping unit for clamping said first member to said second member to constitute ink passages with said grooves, said method comprising the steps of: preparing said clamping unit, wherein said clamping unit has a plurality of clamping portions arranged along the array of said ejection outlets, each said clamping portion having a through hole and a rear end, and each said clamping portion applying a clamping force; applying a releasing force to each of said clamping portions in a direction causing a release of said clamping force exerted by said clamping portions, said releasing force being applied by engaging a tool member with said through holes; placing said first member onto said second member under said clamping unit, after said step of applying said releasing force; and releasing the releasing force so that said clamping portions clamp said first member and said second member together.
