PROBLEM TO BE SOLVED: To provide a highly reliable liquid droplet ejection head excellent in dimensional stability and chemical resistance, and allowing printing of high quality over a long period, and a liquid droplet ejector of high reliability provided with the liquid droplet ejection head. SOLUTION: A inkjet type recording head 1 includes a substrate 20, a nozzle plate 10 provided on an under face thereof, and provided with a nozzle hole 11, and a sealing sheet 30 provided on an upper face of the substrate 20, the substrate 20 is joined to the nozzle plate 10, via a joining film 15, and the substrate 20 is joined to the sealing sheet 30 via a joining film 25. The respective joining films 15, 25 are provided respectively by drying liquid materials containing a silicone material. The respective joining films 15, 25 exhibit adhesiveness resulting from surface activation when applying energy onto the respective joining films 15, 25. The substrate 20 is joined to the nozzle plate 10, and the substrate 20 is joined to the sealing sheet 30, by the adhesiveness. COPYRIGHT: (C)2009,JPO&INPIT
