Abstract:
1. A method of manufacturing an inkjet head, comprising: a step of bonding a surface of a first plate having an ink passage hole penetrating the first plate, to a surface of a second plate by pressurizing a stack of the first plate and the second plate in a thickness direction at a predetermined temperature that is between 900 degrees Celsius and 1050 degrees Celsius; a step of forming a throughhole penetrating the second plate, that is performed subsequent to bonding the first plate and the second plate, wherein the throughhole is communicated with the ink passage hole at a contact face between the first plate and the second plate and opens at an ink-discharging surface that is opposite the contact face; a step of forming a water-repellent film on the ink-discharging surface, that is performed subsequent to forming the throughhole; and a step of heat-treating the formed water-repellant film for stabilization.
