Liquid discharge head

A liquid discharge head comprising:

• a first plate including an individual channel communicating with a nozzle and including a pressure chamber;
• a second plate stacked, in a stacking direction, on the first plate on a side opposite to the nozzle;
• a vibration plate stacked between the first and second plates in the stacking direction;
• and
• a piezoelectric element which is arranged in the vibration plate at a position overlapping, as seen from the stacking direction, with the pressure chamber of the individual channel,
• wherein a part of the second plate overlaps with the piezoelectric element in the stacking direction, and the second plate includes:
• an accommodating space accommodating the piezoelectric element, and
• a pair of communicating channels arranged to sandwich the accommodating space therebetween, each of the pair of communicating channels extending in the stacking direction, and communicating with the individual channel;
• and
• a spacing distance between mutually close parts in a pair of inner circumferential surfaces of the pair of communicating channels, respectively, is greater on a side of one ends in the stacking direction of the pair of communicating channels than on a side of the other ends in the stacking direction of the pair of communicating channels, the one ends being close to the individual channel in the stacking direction.
