Abstract
A droplet discharging head comprises a pressure chamber in which fluid is filled through a channel, and a nozzle that is connected to the pressure chamber and which discharges the fluid as a droplet. After the droplet discharging head is assembled, at least the wall surfaces contacting the fluid are coated with a carbonized silicon film.
