Abstract
A liquid discharge head includes a piezoelectric element, a first holding substrate, a second holding substrate, and damper. The first holding substrate has a recess accommodating the piezoelectric element, a first partition having a first width in a width direction of the first partition, and first side spaces partitioned by the first partition. The second holding substrate has a second partition having a second width wider than the first width in the width direction and second side spaces partitioned by the second partition. The damper is disposed between the first holding substrate and the second holding substrate. The damper has a first surface facing the first holding substrate, a second surface opposite to the first surface, and a penetrating portion penetrating through the damper. The second surface is bonded to the second partition of the second holding substrate. The penetrating portion is disposed adjacent to the second partition.
