Abstract:
1. A method of manufacturing an inkjet head having plates that are laminated, an individual ink passage that penetrates the laminated plates, a nozzle at one end of the individual ink passage in an outermost plate of the plates, and an actuator unit, comprising: a step of forming a communication hole in each of the plates; a step of laminating the plates with thermosetting adhesive therebetween so that the communication holes are overlapped with each other in a plate-laminating-direction, thereby making the communication holes form the individual ink passage and the nozzle; a step of adhering the laminated plates by applying pressure to the laminated plates in the plate-laminating-direction while heating the laminated plates; and a step of laminating the actuator unit with thermosetting adhesive onto the laminated plates so as to cover the communication hole formed in one of the plates that faces the actuator unit, wherein the actuator unit laminating step is performed before the adhering step, and wherein, in the adhering step, the actuator unit and the laminated plates are adhered simultaneously by applying pressure to the actuator unit and the laminated plates in the plate-laminating-direction while heating the actuator unit and the laminated plates.
