Beschreibung
Zusammenfassung:	A liquid ejecting device has a fluid passage structure formed with multiple nozzles and multiple passages respectively communicating with the multiple nozzles. The fluid passage structure has a nozzle plate formed with the multiple nozzles, and a passage body laminated and bonded with the nozzle plate, the passage body being formed with multiple individual passages respectively communicating with the multiple nozzles, the passage body being formed with provided with multiple convex parts made of a material harder than the nozzle plate. The multiple convex parts protruding toward a nozzle plate side, and the multiple convex parts are covered by the nozzle plate. Further, the multiple convex parts protrude with respect to a liquid ejection surface on which ejection openings of the multiple nozzles arranged.
