Abstract:
1. A method of manufacturing an ink jet print head comprising: a first step of preparing a print element substrate, a support member for supporting the print element substrate, and an adhesive, the print element substrate having an ink ejection opening for ejecting ink and an ink introducing port forming surface formed with an ink introducing port for introducing ink to the ink ejection opening, the support member having an ink supply port forming surface formed with an ink supply port for supplying ink to the ink introducing port, the adhesive being applied to at least one of the ink introducing port forming surface and the ink supply port forming surface; a second step of sandwiching the adhesive between the ink introducing port forming surface and the ink supply port forming surface; a third step of increasing a gap between the ink introducing port forming surface and the ink supply port forming surface, with the adhesive sandwiched between the ink introducing port forming surface and the ink supply port forming surface, to elongate the adhesive between the ink introducing port forming surface and the ink supply port forming surface; and a fourth step of hardening the adhesive elongated between the ink introducing port forming surface and the ink supply port forming surface.
