PROBLEM TO BE SOLVED: To provide a manufacturing method of a liquid discharging head capable of alleviating deformation caused by thermal expansion upon the bonding of an ink feed member with a recording element substrate and capable of alleviating misalignment upon the bonding of the recording element substrate. SOLUTION: In the method, the recording element substrate 002 for discharging liquid and the liquid feed member for feeding the liquid to the recording element substrate 002 are coupled with an adhesive agent which contains at least an infrared ray absorbing agent and is hardened by an ion polymerization reaction mechanism, and the recording element substrate 002 includes a silicon substrate 008 to make the adhesive agent irradiated with light including at least an ultraviolet region to an infrared region pass through a filter composed of silicon.
