Abstract
A method of manufacturing an ink jet print head capable of bonding the printing element substrate to the support surface with high precision in a reduced period of time is provided. For this purpose, raised flat portions are formed in the support surface of the supporting member to provide in an adhesive layer between the printing element substrate and the supporting member a portion of the thermosetting adhesive that is thinner than others. After the relative positions of the printing element substrate and the supporting member are adjusted, the thin portions of the adhesive layer are hardened. This enables the printing element substrate to be bonded to the supporting member in a relatively short period of time. As a result, if there are undulations on the support surface, the printing element substrate can be bonded to the supporting member with high precision, improving the mass productivity of the print head.
