A liquid discharge head, comprising:
- a nozzle defining member including a plurality of nozzle arrays, each of the nozzle arrays including a plurality of nozzles aligned in a first direction, and the nozzle arrays being arranged side by side in a second direction intersecting with the first direction;
- a channel defining member defining a channel in communication with the nozzles;
- a connecting part including a plurality of contacts located on the channel defining member;
- a trace member electrically connected with the contacts;
- a plurality of energy generating elements overlapping with the nozzles, respectively, in a third direction orthogonal to the first direction and the second direction;
- and
- a film covering the channel,
- wherein the plurality of nozzle arrays includes a nozzle array A that is nearest to the contacts in the second direction and a nozzle array B that is furthest from the contacts in the second direction,
- wherein the channel defining member includes a first end and second end which are both ends of the channel defining member in the second direction,
- wherein the nozzle defining member is stacked on the channel defining member in the third direction,
- wherein the contacts are located between the first end and the nozzle array A in the second direction,
- wherein none of the contacts are located between the second end and the nozzle array B in the second direction, and
- wherein the connecting part is located nearer to the first end than the second end in the second direction.
