<p><P>PROBLEM TO BE SOLVED: To provide a droplet discharging head, a method for manufacturing the head, and a droplet discharging apparatus, which prevent a discharged liquid from being permeated into a junction, improve durability of the droplet discharge head, and have no limitation on the types of discharged liquid. <P>SOLUTION: A nozzle substrate 143 provided with a nozzle opening 147 for discharging liquid L as droplets, a channel substrate 142 provided with a channel R of liquid L for communicating with the nozzle opening 147, and a diaphragm 141 constituting the wall face of the channel R, are laminated and jointed together through an adhesive. The liquid-contact surfaces 143r, 142r, 141r, which come into contact with liquid L, of the nozzle substrate 143, the channel substrate 142 and the diaphragm 141 are formed in series with a liquid resistance film C having resistance to liquid L. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
