Abstract:
1. A method for manufacturing a recording head including a recording element substrate, an electric wiring substrate, and a retaining member for retaining the recording element substrate and the electric wiring substrate, the recording element substrate including recording elements configured to generate energy used for ejecting liquid and a plurality of electrodes, the electric wiring substrate including a first insulator, a second insulator, and a plurality of wires disposed between the first insulator and the second insulator and being provided with an opening in which the recording element substrate is disposed, the method comprising: welding the electric wiring substrate and the retaining member to each other by irradiating with a laser beam a contact section in which the second insulator and a surface of the retaining member on which the recording element substrate is in fixed contact at least at a part of an outer peripheral section of the electric wiring substrate, the contact section being irradiated with the laser beam through a region of the electric wiring substrate where the wires are not arranged in a direction perpendicular to the surface; and connecting the electrodes of the recording element substrate and the wires of the electric wiring substrate electrically.
