Patent ID: 8234787

Claim:
A method of manufacturing a liquid ejecting head, comprising: a first compressing step of forming nozzle communication ports from an actuator to nozzle orifices and heat-compressing one surface of a supply port plate provided with supply port plate openings for forming the nozzle communication ports and a first film adhesive provided with a plurality of round holes having an equal size and formed in correspondence to the locations of the supply port plate openings so as to match the locations of the supply port plate openings with the locations of the round holes of the first film adhesive; a second compressing step of heat-compressing the supply port plate compressed with the first film adhesive and the actuator through the first film adhesive; a third compressing step of heat-compressing a nozzle plate provided with the nozzle orifices and a second film adhesive provided with a plurality of round holes having an equal size and formed in correspondence to the locations of the nozzle orifices so as to match the locations of the nozzle orifices and the locations of the round holes formed in the second film adhesive; a fourth compressing step of heat-compressing a reservoir plate provided with reservoir plate openings for forming the nozzle communication ports and a third film adhesive provided with a plurality of round holes having an equal size and formed in correspondence to the locations of the reservoir plate openings so as to match the reservoir plat openings and the round holes formed in the third film adhesive; and a fifth compressing step of superimposing the nozzle plate, the second film adhesive, the reservoir plate, the third film adhesive, the supply port plate, the first film adhesive, and the actuators in this order so that the holes form the nozzle communication port to perform heat-compressing.
