PROBLEM TO BE SOLVED: To provide a liquid discharge head excellent in liquid tightness.SOLUTION: A method of manufacturing a liquid discharge head includes: a step of arranging a sheet member having an adhesion layer and a protective layer on a support member having a flow passage so that the adhesion layer comes in contact with the support member; a step of irradiating the sheet member with a first electromagnetic beam from a protective layer side to form a through-hole communicating with the flow passage; a step of irradiating a part of the adhesion layer with a second electromagnetic beam to cure it; a step of removing the protective layer; a step of arranging a recording element substrate on the adhesion layer; and a step of curing the adhesion layer.SELECTED DRAWING: Figure 1 |
