Abstract
A method for manufacturing a liquid ejection head includes joining a support member to a print element substrate using another member to which the print element substrate is attached. The other member has a suction region to be held at the time of being attached to the support member.
Claims6
A method for manufacturing a liquid ejection head that includes (i) an element substrate including a pressure chamber that can store liquid therein, an energy generating element that applies energy to the liquid stored in the pressure chamber, an ejection port that ejects the liquid to which the energy is applied by the energy generating element, and a supply port that supplies the liquid to the pressure chamber;
- (ii) a first member that supports the element substrate;
- and (iii) a second member that supports the first member, the method for manufacturing the liquid ejection head comprising:
- an element substrate joining step of joining the element substrate to one side of the first member, whose area is greater than that of the element substrate;
- and
- a first member joining step of holding a holding area provided on the one side of the first member by a holding member and joining a back side of the first member opposite to the one side of the first member to the second member.
