A liquid discharge apparatus, comprising:
- 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 crossing the first direction, and
- a channel defining member defining a channel communicated with the nozzles,
- an electric connecting portion comprising contacts arranged on the channel defining member;
- a trace member electrically connected with the contacts;
- and
- energy generating elements, each of the energy generating elements being overlapped with a corresponding one of the plurality of the nozzles in a third direction orthogonal to both the first direction and the second direction,
- 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 has a first end and a second end which are both ends of the channel defining member in the second direction,
- wherein the channel defining member is stacked on the nozzle 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 a distance between the first end and the nozzle array A in the second direction is larger than a distance between the second end and the nozzle array B in the second direction,
- wherein the electric connecting portion is located nearer to the first end than to the second end in the second direction, and
- wherein a length of the electric connecting portion in the first direction is more than half of a length of the first end in the first direction.
