Zusammenfassung:	PROBLEM TO BE SOLVED: To perform highly reliable bonding even in the case that, when a member which is one of members constituting a liquid droplet discharging head and has one surface on which an ink-repellent film is formed is bonded to the other member with an adhesive, an ink-repellent component is attached to an adhesive-bonding surface.SOLUTION: A liquid droplet discharging head includes: a nozzle plate 11 having nozzle holes 40 through which liquid droplets are discharged; and a frame 4 that is bonded to the nozzle plate 11 with an adhesive 16 at a bonding surface opposite to a liquid droplet discharging surface of the nozzle plate 11. An ink-repellent film 10 is formed on the liquid droplet discharging surface of the nozzle plate 11. Openings 27 penetrating from the bonding surface to the liquid droplet discharging surface are formed in the outer peripheral portion of the nozzle plate 11. The adhesive 16 is spread between the frame 4 and the nozzle plate 11 in the openings 27 on the outer circumference of the nozzle plate 11, and between the openings 27 and the outer circumference on the liquid droplet discharging surface to cover ribs 29 formed at the outer peripheral portion between the openings 27 and the outer circumference.
