Abstract
A droplet discharging head comprises: a cavity substrate including a discharge chamber having a bottom wall serving as a vibration plate; and an electrode substrate including an individual electrode that faces the vibration plate with a gap and drives the vibration plate, and a driver integrated circuit (IC) that couples with the individual electrode and applies a voltage to the individual electrode. The cavity substrate includes a first opening that penetrates the cavity substrate and serves to house the driver IC, and an insulation film formed on a wall face of the first opening.
