Liquid discharge head, liquid discharge device, and liquid discharge apparatus

A liquid discharge head comprising:

• a piezoelectric element;
• a flexible damper having a first face and a second face opposite to the first face;
• a first holding substrate bonded to the first face of the flexible damper in a bonding direction, the first holding substrate having:
• a recess accommodating the piezoelectric element;
• a first partition having a first width in a width direction orthogonal to the bonding direction;
• and
• first side spaces partitioned by the first partition, the first side spaces facing the first face of the flexible damper;
• a second holding substrate bonded to the second face of the flexible damper in the bonding direction, the second holding substrate having:
• a second partition opposed to the first partition via the flexible damper, the 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 second side spaces facing the second face of the flexible damper;
• and
• openings at both ends of the first partition in the width direction, the openings respectively opposed to the both ends of the first partition via the flexible damper.
