Abstract
A droplet discharge head is provided. The droplet discharge head includes: a discharge port through which a droplet is discharged; a liquid channel which communicates with the discharge port; and an actuator which includes a deformation layer defining a part of wall surfaces of the liquid channel and an electrode facing the liquid channel through the deformation layer, and which causes the deformation layer to deform toward the liquid channel when a drive signal is supplied to the electrode. A groove is formed on a surface of the electrode opposite to the deformation layer.
