Abstract
A liquid discharge apparatus in which controllability of liquid discharge speed is improved is provided. A pair of electrodes is arranged so as to divide a partition into a movable region to which an electric field for shear-deforming the partition at a portion on a nozzle side is applied and an immovable region to which the electric field is not applied at a portion on a common liquid chamber side. It is assumed that a cross-section area of a cross section along a face perpendicular to a longitudinal direction at a second end of an individual liquid chamber is S2, and a cross-section area along a face perpendicular to the longitudinal direction at a first boundary point closest to a first end on a boundary between the movable region and the immovable region is S1. The cross-section area S2 is made wider than the cross-section area S1.
