PROBLEM TO BE SOLVED: To provide a droplet discharge head for which the frequency of recovering treatment accompanied by wiping is reduced, and which can perform the stable discharge of liquids for a long time, to provide a method for producing the droplet discharge head, and to provide a droplet discharge device. SOLUTION: In the nozzle face 22a of a nozzle substrate in a droplet discharge head for discharging functional liquids from a nozzle 21 as droplets, the circumferential region including the opening part 21a of the nozzle 21 is subjected to lyophilic treatment in such a manner that its lyophilic properties increase as it approaches the opening part 21a. Then, the outside of the region subjected to the lyophilic treatment is subjected to liquid repellent treatment as substrate treatment. COPYRIGHT: (C)2006,JPO&NCIPI
