PROBLEM TO BE SOLVED: To provide a liquid droplet ejection device capable of preventing a liquid repellent layer from separating, even if a liquid droplet ejection face is not covered with a fixing plate at the end of a nozzle plate, and to provide a method for manufacturing a liquid droplet ejection device.SOLUTION: In a liquid droplet ejection head 10, a liquid repellent layer 17 is continuously formed from a liquid droplet ejection face 1a to the halfway position of the thickness direction of the end faces 101 and 102 of a nozzle plate 1. Consequently, a wiping member 4 butts against the nozzle plate 1, the wiping member 4 does not butt against the edge of the liquid repellent layer 17. Consequently, since even the ends 106 and 107 of the nozzle plate 1 located on the starting point side of wiping by the wiping member 4 do not need to be made a structure in which the liquid droplet ejection face 1a of the nozzle plate 1 is superposed on the fixing plate 18, the size of the nozzle plate 1 can be reduced. |
